@@TunerwithKids May I know if you have had such issues with brake calipers before?

😂😂😂
I have a is250 07 and I appreciate you making these how to videos. You save me a lot of money and time. Stay healthy and safe my man.
Glad to do them. I’ve been doing this forever but used to post on ClubLexus but with videos are much better to illustrate the process.
I just picked up a 2 is 250 this year . I am eager to perform many of the upgrades you have featured on your channel. Thanks for taking the time to share your insights and love for this fabulous vehicle.
Thank you so much for recording the process, I just did this upgrade myself and it was very well worth it. Your tutorials are awesome keep up the great work
Did u have to use spacers or it just fits with the wheels?
Stock wheels fit IS350 calipers. Aftermarket is YMMV based one design.
Thanks man on the awd 2012 rotor statement.Makes a great difference and well worth it ❤ 🙏🏼
Great video, informative and well shot
Love the way that you recorded this with a second camera looking from under the car.
Beware that there are shims between the caliper and the aluminum knuckle. They tend to stick to the caliper when separated, but may also fall onto the ground.
Nice to work on a clean car like that. You clearly do not live in the rust belt.
Just got a 2011 is250 and the wife is complaining about the breaks not being the best. Took it for a test drive and it can definitely get more stopping power for sure. Gonna go the same route too. Thanks for the video and the details.
this is affordable and easy upgrade for IS250 especially if it is rotor and pad time too. Millions of rotor options out there now for the 350.
Tuner with Kids how does it feel now? Does it stop better? How’s the petal feel?
I don’t know since I really did this DIY to show the process. I have not had IS250 brakes for 11 years. I recently upgraded the IS350 to GS350 14” F-Sport brakes. More for aesthetics as the 350 is more than needed. It will reduce fade and provide a much firmer pedal and feel especially for the spirited brakers.
Lmao idk if you remember me but I’m the guy from the Facebook GC with the non moving car due to the AWD rotor problem. I’m glad you made a video teaching people how to do it so they don’t have to go through what I had to go through.
Yep...I didn't even know it was an issue until I saw your posts. Probably helped alot of others from making that mistake now.
@@TunerwithKids I’m about to do this conversion on my awd is250, am I going to run into this issue?
@@justinschultz6482 , make sure to order 2012+ USA spec rotors. They have the hub vents on backside and fit the axles.
Damn Ok thank you, I already ordered rotors for a 2008, I’ll have to exchange them I’m assuming
If they are RWD and have hub vents on front, then yes, they are wrong.
This is cool, I always wanted to do this on my IS250, but I went ahead and bought myself a 350.
good plan.
Tuner with Kids lol. I always found it difficult to get a pair of big brakes form the 350, gs350, or even the ls460 in my area. And eBay is really expensive. Where did you get yours?
junk yard or Rock Auto. eBay has the calipers for $300 no core return (which is about the same price as Rock Auto without the core returned). ebay.to/2skMcIq
Well aren’t you just exceptional .
Thank you sir!
Turn the wheel for better acess and always change out the pads!
Great video!
I just got my caliper upgrade on my is250 today...
thank you
can you only run the small 12"s? or can you fit the 13.1" ones on there do you know/did you try?
Hey man! Great job 👍 I really appreciate your videos😁
Do you have the part no. for disc covers?
Cheers!
Check the parts list in description box. I should have listed everything needed.
Thanks for the video! Very easy to follow!
Question - I noticed you did not install shims. I guess it's not required unless it squeal/squeaks?
Pads have two OEM shims on them.
Will my 250 is 17" stock rims rub on upgraded 350 is front calipers?
Hi break pad front is 250 2011 fit in gs 350 2011 calipers
Always love to see you working on your is250.i have one question.does the torque spec for the banjo bolt also apply for the standard caliper?and the other torque specs also?
Yea same bolt sizes.
Where can i get the same size lexus sticker you used ?
They won’t fit an 18 inch wheel???
I'm going to upgrade my IS250 AWD brakes thanks to this video. Though what did you do for the rear brakes and rotors? Is there a 350 upgrade as well?
I have 350 calipers and rotors in rear. Had to modify the backplate.
Planning to do this on my 2012 is250 AWD, I purchased some is350 front calipers, what year rotors should I run? 2012 AWD gs350 rotors? Don’t want to mess up and get the wrong rotors
2012 USA spec IS350 fit both AWD and RWD.
I have an 09’ IS250 RWD...what year IS350/GS350 brake system should I get? Or what years are interchangeable to install on the IS250.
All years from 2006 to present will work. All rotors too. The ones to be careful of is if yours is an AWD, then you will need certain year rotors to fit.
Hey just bought my first 2010 IS250 awd base and jus found your Chanel and subscribe do u have a parts list for the awd option
Parts are basically same except you have to get 2012+ USA Spec 350 rotors, those are AWD compatible. Else you can find GS or newer IS350 AWD rotors. You can sell cause the hub area is vented in the back vs. RWD that is vent up on front side. I'll post some links in the video to some AWD rotors.
Hello
I have a 2008 IS250 RWD, which brake calipers can I look for and which ones fit perfectly?
Thanks
Everything I showed will work and bolt on.
Hey sorry to ask so many questions but I just want to be safe than sorry. For this upgrade are the only pieces I need are the calipers and baking plates? I just want to make sure I don’t need a 350 hub or bearings and whatever else could possibly be needed?
You need rotors too. Hub is all same. The backing plate/dust shield is optional. You can cut and bend the 250 ones to work.
Great tutorial!! I really want to do this upgrade. I have a question though, I have a RWD 2011 is250, does it matter what year is350 brakes I get and do the break have to come from a RWD model as well???
If yours is RWD, you will be fine with any year from 06 to now.
@@TunerwithKids so I can have calipers from
RWD or AWD as well?
Great do u have those part members again my guy??
Look in description box of video.
Hi Binh
Enjoy your clips
Like your 🚗
Im in Aust. but the info is still relevant -same car
Ive recently bought a 07 is250 manual & its really helpful to see owners working on their car's themselves
Could you point out where exactly are the lift & jacking points on the car. Im too scared to jack it up atm cos i dont know exactly where is safe
Thanks
Mike (AU) :)
Hi Binh
Thanks big time for showing where to jack up the car. That magnetic puck is brilliant. Big Thanks my man
Cheerio & keep up the excellent work 😀👍
So I would need 350 Pads as well? I’m assuming I order Pads, Rotors, calipers, dust shield and I can do this myself?
Yes. Need pads and rotors for 350 in brand of your choice.
“Can you trust mechanic in sandals?” Only if he/she is an asian haha
Perfect tutorial, thats what I was looking for. Cheers
If using back the 250 dust cover, how do u cut it? And bend it?
csa yes, cut the lower corner and push back the area that touches the rotor.
Hey man so what would I have to go with for my vehicle I have a 2015 Lexus IS 250 awd 18inch option
Need same Gen rotors since all 3rd Gen 350 rotors clear AWD.
Thanks for the tutorial - I’ve been toying with the idea of doing this swap for a while and you’ve cleared up a bunch of questions I had.
I do have one question for you: does the OE IS250 brake master cylinder have any issue keeping up with the dual piston caliper? Or do you recommend upgrading that as well?
They use the same MC.
Hello. Thanks for the awesome tutorial videos. I have a question for the front rotors. I have a 2010 AWD IS250, If I buy a 2010 USA Spec Rotors, would that perfectly fit the 2010 AWD IS250? Let me know if the 2010 usa spec rotors will fit. Thank you.
Get 2012 USA spec 350 rotors , they work on both AWD and RWD
@@TunerwithKids Noted. Thanks for the response. Keep up the good work and great videos👍
Hey I ran into an issue. When I installed the brake and rotor the driver side started to shake when braking. I tried replacing the rotor, brake pads, and caliper. Each time feels like brake pads shaked . I even bleed the caliper. Every bolt was tightened and double checked. I’m at a loss and about to shake the hub too right after the bleed the whole system. Any thoughts or solutions?
Did you check make sure there isn’t any damage to the hub assembly? You can try to unbolt that and make sure there is no visible damage. Only other thing might be worn bearings.
you have to measure hub runout... it cannot be bigger than 0.02mm... you should clean your hub perfectly, same measurement with disc mounted.. you have to measure it again, disc runout cannot be bigger than 0.05. If your hub is not perfect (runout bigger than 0.02mm) try positioning the disc another way and measure again..maybe you will be able to compensate both runouts hub/disc and stay
I have ESR 07 18x9.5 +35, would they fit with the bigger calipers?
No idea, its about the hub spacing from spoke
why you did not measure the hub and disc runout???? I also tough that the hub needs to be cleaned (surface) from the surface rost? I am just upgrading my is250 with 350 calipers but I am worried about the runout.... and my hub was stuck as f**.... I managed to press it out using 2 screws and pushing against the old rotor and the caliper mount "ears" (sorry for my english) .. hope did not damage anything.
My car is a FL car, so no rust of corrosion to deal with. That minor surface rust isn't anything as it will happen to cars anywhere due to the iron rotors and steel hubs.
Do you really need the shield for the backing? What will happen if you don't put the shield? I just thought that it looks nicer without it and more cooling I would think?
You can use the 250 one and trim and bend to fit. Don’t remove all together because the hub needs that as a spacer. Another guy I saw on FB took it off and the rotor was rubbing the calipers.
Tuner with Kids Thank U so mch for your input!😊👍🏽
I have the OEM 17 inch wheels. I read on a forum that the IS350 calipers would not clear with the 17 inch wheels.. Is this true? Do I need at least 18 inch wheels to clear? Thanks.
The OEM 17 for IS fit. Like the ones that come with AWD and others. Aftermarket 17 will be hit or miss due to the disk height.
why dont you turn the wheel to make it easy
Have you found a std oem upgrade for the rear brakes?
For a 250, you can do 350 rear calipers and the larger center rotors. It’s same pad.
Hi...I am from Malaysia. May i know what is the size (diameter) of the IS350 rotor?
I just upgraded my Malaysia's version Toyota Camry XV50 stock front brake to bbk, using Advics caliper maybe from Lexus GS350 or IS350 (i guess, not really sure because it is an imported used one) with 355 mm rotor, and the rotor is really heavy compared to the stock rotor...
356mm is the OEM GS350 4-piston brakes.
@@TunerwithKids alright tq
I have an 2008 is250 rwd, and want to Upgrade front calipers and rotors. is350 f sport brakes and rotors will fit?
Yes...this is exactly what this video was about. IS350 Fsport or non is the same caliper/rotor combo.
Hey binh, so I can run any rotor/caliper setup from 2006-2023? I have a rwd 2011 is250
Yes. All the same calipers and brakes.
Is that an actual Lexus caliper or is that a refurb that you painted? I can't for the life of me find an actual 350 stock caliper ANYWHERE.
Sidney it’s a refurb. They are everywhere these days. Just got to local auto parts or Rock auto. eBay too, I have some links.
Do u have to bleed all the brakes or just the fronts after you change the front rotors and calipers?
All need to be bled. It’s also a good time to flush the system. Usually want to replace brake fluid every 3 years since it absorbs moisture over time.
Quick question can I still the same rotors that the oem brake system of the is250 has? I'm asking because I purchased drilled rotors for the 250 and don't wanna have to spend more cash on rotors
Never just got the part where it says they're about an inch difference
Hi, this might be a stupid question but..
can you confirm that the diameter of the is350 rotors is 334mm? I'm having trouble finding the dimensions.
Thanks
That sounds correct. It’s 13.1 inch so whatever that equals in mm.
Hi do think big Break update fit 2007 Scion tC want good stopping power
Scion Tc wouldn’t work with this. These are for RWD cars.
Well 17 inch wheels fit over this upgrade?
OEM 17s but not all aftermarket. Its all about the disk height.
Hey question, I’m on rock auto trying to order a rear and front set of rotors for 2012 is350 and there different colors lol. We’re you able to find the same color?
It’s all random based on brand and grade. Best bet if you want to match is to sand and paint the center hub areas in a high heat black. It will protect from corrosion. All other areas of the rotor will rust anyway.
i dodnt see after but do you need to run spacers because the caliper is bigger or does the wheel clear enough for the caliper ?
OEM 17 and 18 fit.
Hey, Tuner I’m interested in doing the IS 250 to 350 caliper swap but I would like to also swap the the rear calipers as well. What’s the process on the rears if you have any idea? Or planning on doing the same as well. Thanks
What year is yours? The upgrade isn’t that significant so unless you need calipers and rotors, not really worth it. The IS350 parts bolt up, the dust shield needs to be bent since there isn’t an easy way to remove, plus the part is over $250/each.
Tuner with Kids 06 Lexus IS 250. I already have the Rear calipers from a IS 350.
If you already have then it’s bolt on. Make sure you have the brackets too. Need a set of is350 vented rotors and you are good. It uses the same pad as IS250.
Great video 👍 but I want to double check if I could do this on a 2015 fsport?
Yes. These brakes fit all IS models from 2006 to 2020.
@@TunerwithKids I have a 2021 350 F sport. I’m trying to do this to the rear ones. Any idea if they’ll fit ?
The 2021 350 already has these on front. Check 350phi.com for adapter to used ISF or GSF rear calipers.
IS your car an AWD, if not, do those brake dust sheilds fit 250 AWD for this upgrade? Also where did you get the decals for the refurb calipers? Thanks
I’m RWD. Not sure on what shield are needed for AWD. You can probably order the newer IS350 AWD shields. Decals can be found all over eBay for like $5.

Cardone 2 PCS Front Left & Right Disc Brake Calipers For 2006-2007 Lexus GS430 Will work on an IS250 2014 Base Model? I put my vehicle on eBay and it says not compatible, but When I put 2014 IS350 it says compatible. Any help? Thanks!
Yea it will fit. All 13.1 monoblock brake calipers from 06 to present are the same. It said not compatible probably cause you put 250. Since you are upgrading to 350, need to assume you have a 350.
Tuner with Kids okay so I found my nearest junkyard has a Lexus GS350. Will I be able to use those if I take them out?
Yea. As long as it has the Advic monoblock calipers still on it.
Hey man are you had brake bleed after done or not .
Yes you have to replace fluid when changing calipers (or every 3 years).
I have a 2015 Lexus is250 rwd fsport where can I buy the 350 calipers?
Rock auto, eBay (check link in description), or local part store. The calipers are same from 2006 to present and used in GS and RC so plentiful. Average price is $75-$80 each plus return an old core.
Do you know if this upgrade can work on the rx350 2017 fsport?
There is the new RX Fsport brakes which is 100% bolt on but requires 19 or 20 inch wheels.
I have 18s but after market
Do you know if this big brake upgrade fits on IS - 2014 and up ?
Yea. IS has same front brakes since 2006
I was talking to my mechanic and he said the existing wheel hub does not fit onto the IS350 dust shields. I got the shields with the same P/N as your description. Do I need to change the hub as well?
Naw. There’s no reason why it won’t fit. I had IS250 shields, IS350, and now IS-F shields. They all fit. You have to remove the hub, tuck the shields on and bolt back down.
@@TunerwithKids Thanks for the quick response! I had gotten the call about it from my mechanic since he’s trying to remove the wheel hub for me a few minutes ago and that’s what he said. I’ll get it figured out. Thanks!
Where did you get your backing plates. I can’t find any junk yard with 350s. Is there a website you got them from or are there website where you can get them from? How were you able to get your hands on them?
Try Bell Lexus Parts in Scottsdale, probably best value and free shipping for $100+. I’ve been getting all my hard to find OEM parts there. The dust shields are like $45/each.
@@TunerwithKids awesome thank you so much!
Is it possible for me to use the 14" dust shields on 13" rotor setup without modifying anything ?,or is the dust shield to big ?
It will work. The 14” is ISF so the bumps and cooling is slightly different. The 13” is IS350 shield.

is that brake line from the 350 as well? my 2006 is250 brake line does not have that extra arm attatched to it that feeds that second inlet beside the banjo bolt on the caliper..... can anyone help with this?
The OEM line has the arm. If yours is missing, it’s probably aftermarket replacement. They use same line between 250 and 350

Hi the front gs 350 dust back dust plate fit in is 250 2011 year
The dust shields for GS350/GS430 (2007-2011) will fit.
I have a 2008 IS250. What do I need to upgrade rear rotors to vented rotors like you have.
IS350/GS350 calipers and the larger vented rotors off same cars. It uses same pads.
@@TunerwithKids doesn't matter whst year? Or if AWD? Mine is awd
Thanks again for an awesome video. Do the rear brakes on the 350 fit the is250 as well? If so, I hope you make a video on the rear too someday! Thanks!
They fit and it’s literally a bolt on if you get the full caliper and bracket. Just need to bend the dust shields back. It uses same pads on slightly larger caliper and vented rotors.
@Binh-Tuner with Kids hi, just found your video. I have the is350 f sport sedan 2016 but my brake stopping power is not great. I'm guessing, since I already have the bigger rotars, the only upgrade I can do is the brake pads?
I have 350gs caliper 2009 to 2015 upgrade the is 250 2011 . I have rotor vented for gs 2011 fit? Good? In 2011 is 250
If you are RWD, any 350 caliper and rotor from 2006 to now will work.
Is it OK to only upgrade the front brakes?
Yes.
Question:)
Can i just put calipers from is350 into 2006 is250? Or i need a rotor from 350 as well?
No they rotors are over an inch difference.
@@TunerwithKids So the rotors need to be from 350 also right?
Hi mate. I have been told to get a new caliper for the rear left of the car and also a new pin set? Lexus only have the pins so they told me they will supply the top pin and rubber boot but they said that the bottom pin on their systems its not applicable for the car. Does this bottom pin come with the new caliper? Please let me know. KR
Order a rebuilt loaded caliper with bracket, $50 at local auto parts. The lower pin is seized and very common issue with this car. Need to change out whole assembly with bracket.
@@TunerwithKids I am in the UK. We fit the Pagid aftermarket calliper on and kept the bottom pin from the old calliper even though its got play to it. Got a pin slide kit hopefully that bottom pin is the correct one because it was a nightmare to get.
would the is350 calipers fit gs350 rotors?
They are the same brakes. Only except is 2012+ GS350 F-Sport RWD. They use 14.1 rotors and different calipers.
wait can you explain the “lip” in the rotor ? i have a 13’ is350 and i just got the rotors replaced 4 months ago and it has that groove on the edges. is this a cause for concern or no ?
Aggressive pads will wear these rotors fast.
@@TunerwithKids i had those replaced as well. in 3-4k miles of driving should they be wearing on the edge like that ?
@@mxrmforever probably not. How deep is it?
@@TunerwithKids only a cm or so but its obviously its rounded now and not wearing on just the front of the rotor
I have a 06 IS250 awd and I wanna upgrade what do I need
For AWD, you use the same calipers but you will need AWD IS350 rotors from 2011+ or GS350 AWD rotors. They need to clear the axles on the back side, you can tell the AWD rotors cause the front is hub area is closed vs. the RWD like mine. I think if you order 2012 USA spec IS350 rotors, they will be the AWD versions.
Are the is250 and is350 rear brakes the same?
No. 350 is 0.5” bigger and vented. Same pads though.
Could I downgrade my 350 rotors and calipers to 250's? For weight savings.
Yea but why. If you watch my other video, the 350 is actually same or lighter. Since they are case aluminum.
Hello, Binh!
Mine is 2006 is250 awd, and I wonder if a 2012+ 350 rear rotor direct fit to my rear? Thanks!
Rear rotor is same for all 350s. It will fit fine. Make sure calipers come with new bigger matching brackets.
@@TunerwithKids Thank you for replying! My question is that will 350s rear rotor fit my 250 awd rear without replacing the caliper ? what bracket you are talking about? Can I find it in any of your videos?
@@jiechen7732 you need calipers and rotors.
@@TunerwithKids thank you so much!
Mannnnnnn I bought one of these cars used, with those EXACT calipers (in red) and I cannot for the life of me find them to replace the one leaking.
They are all over the internet. Check my links in description. You can also check rock auto or local parts stores. They ar $75-$90 for rebuilt but have to return the old core.
I tried finding them I winded up getting some high performance ones that are specific for my car I’m gonna throw on and I guess rebuild the ones I do have.
Every shop around here tried telling me I couldn’t do that.
Great tutorial bro, did you do the 350 swap to the rears too??
Yea I have the bigger 350 vented rear rotors and calipers.
@@TunerwithKids yessir, imma do this poor mans bbk on my 250. Did you have to clean up the calipers and put the Lexus logo on top yourself?
These were repainted. When I painted them, the OEM coating was almost impossible to remove, even with aircraft paint stripper but wouldn’t come off. I just prepped and painted with base coat and clear coat.
@@TunerwithKids right on! Nothing beats oem but if you had to choose an aftermarket brand which ones would you suggest?
@@HUIzanoNA like aftermarket calipers? Or pads/rotors? For all the IS’ there’s four OEM caliper and brake upgrades which are cheap. Yesterday Bell Lexus had a crazy sale for $300/each ISF calipers and $280/ea RCF calipers (possibly a price mistake) but I posted in the FB IS groups and probably created a huge ordering surge. They put the price back to normal now of $372 and $348, respectively.
Hi, thanks for this video. I have an 06 is250 awd what year 350 parts can I use?
2006 to present all have same calipers. Need 2012+ USA spec rotors for AWD. The AWD rotors fit both RWD too. But RWD rotors won’t fit AWD.
@@TunerwithKids thanks for the fast response. Really appreciate you!
Weird Question but lets say I want to do the reverse of this on my 2015 is350 f sport, I want the smaller rotors and calipers on the front for fitment purposes and less brake dust for daily driving, this should just be the same process just putting the is250 parts on correct? Basically going from is350 fsport front brakes to standard is250 front brakes, will I run into any issues?
No but that’s just dumb. You’ll still have dust issues with 250 pads.
@@TunerwithKids Ok fair enough but let’s say I wanted is250 brakes on my is350 would everything bolt up properly?
Yes they fit. I’m sure plenty of 250 guys will trade you.
@@TunerwithKids Ok thanks for the help, just wanted to make sure I didnt need any special bracket or part for the conversion
nice work:D is there any improvment,i mean braking power or shorter braking distance?
Big brakes are mostly for looks for daily driving. But on track or hard braking big brakes have less fade and will not heat up as fast.
@@TunerwithKids thank you for fast reply,i have this bending disc issue on my 250 and im wondering if this swap can fix it,i tried so many disc brands but even the brembo can be warped after 3 heavy breakings .Im not a track guy i just drive fast ,the only thing is that we dont have this is 350 model here in Europe..
Do you have GS350 or RC350? Same brakes.
@@TunerwithKids gs 300 and 450h,maybe gs 430 :)
The GS430 and 450h use same brakes as IS350.
Quick question what about the rear is it the same caliper and disc size in the rear for the 350 n 250
No. Same pads different size calipers and rotors. Plus vented on 350
Thank you
great video. so i have 2010 IS250 AWD. Rotors and Caliper OEM from IS350 will fit ?
Yes with 2012+ USA spec rotors. They are made for both RWD and AWD.
@@TunerwithKids Another question, what about the bolts and nuts. Which should use the Is250 or Is350. I have heard that the thread is not the same as the long ones
EЯиʂɬ , all the same bolts.
@@TunerwithKids so to upgrade my 2010 IS250 AWD, I can buy 2020 Is350 rotor and caliper, with the shield
The rear Brake Caliper Pin of my 2008Is250 can't rotate, I need to change the caliper, I want to ask is the rear caliper of IS250 and IS350 the same?
No they calipers and brackets are different. Pads are the same.
@@TunerwithKids ok,thank
@@TunerwithKids So, can I fit 350 front brake calipers with 250AWD?
Great video but I have a question ? Did the is350 brake conversion bolt right on with the same bolt measurements as is250?
yes, 100% bolt on with IS350 calipers, rotors, and (optional dust shields).
Just bought a 2014 is 250 , the braking is crappy I’m coming from a g37 sport with big brakes, I was thinking of doing this upgrade but adding 20lbs to each front wheel and maybe 15 to rears , plus I want to upgrade to 19 wheels =more weight to wheels for a already slow is250 I dunno 🤷♂️ nevemind
It’s only a 7lbs difference per front corner to go IS350 BBK. The rotors are 10lbs more but IS350 aluminum calipers are 3 lbs less than IS25” cast iron.
Also, rears don’t need upgrade. I think rear might be same 12.2 vented on all 3IS (Fsport). Base model has 11.7 solid. Not worth the upgrade unless you can get it free.
Ok my bad for some reason I took the 350 calipers to be 9lb heavier, and I read that the rears are different a bit bigger and thicker rotor , some people were saying u can upgrade the fronts and leave the rears some said it could be dangerous.
Naw...rears don’t do any rear stopping. It uses the same pads between the 12.2 and 11.7 with a slightly wider caliper and different bracket. The bigger rotors are vented vs solid. But overall no rear world difference.
Hey Tuner with kids, I recently bought rwd Lexus is350 calipers for my 2006 rwd Lexus is250. I was wondering if I can keep the stock is250 rear calipers and rotors with the front upgraded to the is350 rotors and calipers? Also if that works, am I able to put the rear Is350 rotors with is250 calipers in the back or will they have to be is250 rotor and caliper?
You’ll be fine with 250 rear. To upgrade you need new rear 350 rotors and calipers. They use same pad though.
@@TunerwithKids Ok thank you, that helps me a lot. One more thing if you don’t me asking, I found a good deal on a four pack of is350 rotors for the front and back but I was wondering if my 250 rear caliper will fit the rear 350 rotor?
No they don’t fit. The 350 are bigger.
@@TunerwithKids ok thanks, I appreciate all your help
Was the bleeding order correct?
I don’t think it matters. I’ve always bled brakes in circular order and never had issues. I always got thru at least twice to make sure.
Where do I get the same black lexus calipers for my front and rear like the one you installed on your vehicle ?
Paint or powdercoat.
@@TunerwithKids where can i buy the same black lexus calipers though ?
They stock or rebuilt versions from auto parts store will be grey wrinkled coating. Or bare painted silver. You need to get them painted or powdercoat and put a Lexus sticker on.
Can you only upgrade the front but leave back ones as is?
Yea the rear isn’t much of an upgrade. You get like 0.5” gain and vented rotor vs solid. It still uses same pads.
@@TunerwithKids ok so what do i need to get for my 2010 awd?
2012+ 350 rotors with the hub vents on rear. Any 350 caliper from 06 to present.
Would this work on a awd 250?
With 2012+ USA spec rotors.
