Video of the 5 things I hate about the Lexus ISF. Check out the video of 5 things I love about the Lexus ISF. ua-cam.com/users/edit?o=U&vide... IG: @isfaster
I just did a similar video a couple of weeks ago. Figs make an oil cooler kit for the F (you probably already knew that). But nice seeing others making ISF videos, were a rare breed.
Yup, this video has been on my to-do list for a while and finally got some time to making it. I mention the RR-Racing and Figs auxiliary oil coolers but I think it's a joke how quickly our cars oil temps get so hot on track in warmer weather. Lexus should have addressed this issue before the release since they had to have had this same issue during testing. It was only recently that the auxiliary oil coolers were released so for years ISF owners were SOL. Glad to see you are making videos too! We've gotta spread the word!
Great to hear! Always great to hear/see other F cars on track. It’s almost like seeing a unicorn! Try it without the oil cooler first and see how she does in your climate and tracks.
All valid points from your experience with the F. It’s like grasping at straws to come up with top five gripes for me, but her goes: 1) Brake dust from stock pads, breaks are awesome just more dusty . 2) Shifter doesn’t have a boot cover. Seeing the gate looks cheap. If it had a cover, I would say the interior is perfect. 3) Narrow tires from factory, easily fixed. I run 245 out front and 275 rears for the summer setup. Actually, can only come up with three items that are a little annoying, that’s it. The F is a great balance of power, handling, and reliability.
Nice. You're right, it's a good all around vehicle, jack of all trades and master of none. I remedied the stock pad brake dust with new Project Mu NS400 pads. They're great for street use and hardly any dust.
In the development of the ISF video you can see the oil at 5 bars running at Fuji. And in the summer Fuji gets way hotter than Cali. So the engineers did see the oil getting hotter but I guess they didn't think it was a concern.
2013 ISF here, all valid points, however the oil issue can be addressed with a quality synthetic oil like Redline 5W-30. The stock headers are known to crack, so yes, replacing them with PPE or Sikky works well and gets you a lot more power. The rear seat? well, unless you're 6'3, you'd be ok.
Have you personally ran your car on a road course for a full 20+ minute session at full throttle on an 80+ degree day and not had any oil overhead issues with that oil? If so that would be great to hear as I would love a fix that doesn’t include the known fix of having to buy and install an auxiliary oil cooler. Thanks.
do the tires stick out past the fenders? i watched another video about the rcf and how lexus had to add this weird little extra tab on the fender in the rear because supposedly its illegal for the tires to stick out past the fenders. no idea if thats true but just a thought
More than likely it’s the pad. I hate hearing that sound during normal street driving too. My track pads squeal but have a lot better bite and heat resistance so it’s a trade off.
Cool videos man. I have a 2012 ISF too. You mentioned you upgraded to wider tires...but also had new springs. You think there would be any fitment issues with out the new springs? I wouldn't think so... What's the aspect ratio of your front and backs? Thinking about upgrading my tires as well.
@@ISFASTER That's good to hear. Do you believe the IS350 has a restriction in the exhaust?? Do you have any drone?? I'm thinking about going with Xforce or Tannbe
Not too sure about the IS350. I will get a slight drone in 8th gear going up a gradual hill like on a freeway but can easily be fixed by shifting down and punching it. 😁😁😁
Nice Video, My ISF has the intake and PPE headers full on exhaust system. The only thing I hate is when I come to a stop on traffic light, someone thinks I want to race. Most people here on Guam think my ISf is either a 250/350 moded with ISF body kit. But when they hear the motor rev they know it's not a Badged F car. It is a sleeper car, that would have gotten recognition if Lexus tuned it at least 500bhp N/A . Just the thought would have made a huge difference for the market, I am sure Lexus was still remaining to the Luxury heritage and had to detuned the output bhp to comply with US standards and be salable. That's where import tuner companies make their $$$ by providing the aftermarket upgrades. It will be nice to take on the shelby mustang, hellcats, track hawks, Corvette z06/Zr1 and BMW M5. But when their superchargers or turbo chargers kick in, on a freeway race the ISF can only keep up... I still believe it's more on the driver than the car itself.
Probably my biggest gripe with this car is it doesn't have a good sport automatic mode. It's pretty obvious the trans logic is to get in as high a gear as fast as possible. Even with sport mode engaged, it takes forever to downshift when you punch it because you're cruising around town in 8th gear! Oh, and a nice analog clock would've been nice.
I agree with how long it takes to downshift when punching it in 8th but during spirited driving it’ll hold gears in corners and deceleration fairly well. I usually move over to manual mode though.
@@ISFASTER Yeah, sport auto is pretty good when punching it from a stop. Agree about the stock tires, they often struggle for grip but getting wheelspin in 3rd gear on dry pavement sure is fun!
Lack of camber is the part that drives me nuts. My SC400 has adjustable camber. Not too crazy but enough. Crazy to see that they didn't give us the option with the ISF. Those are some really important mods!
When and How much did you guys pay for your ISF? Also how many miles? Lastly What year do you guys have? I’m a 19 year old and I’m thinking of buying a isf by the time I’m 21
I think the main issue is Lexus really didn’t make these cars to be sports cars alone like a mustang are camaro they still tend to lean toward the luxury and reliability side of things, maybe the RCF are the GSF you get better performances but your now talking about $40,000 to 50,000 grand
Yea japan gets hot as fuck. I’d say temp wise it’s close to southern ca/la in the summer but its considerably more humid. Close to Florida levels of humidity. So I’m sure they experienced the oil heat issue. There’s no way they are changing the oil every 8-10 laps
No doubt Toyota/Lexus is conservative, especially with change. At the time of release of the ISF they had no performance vehicle classed above it in the Lexus lineup so it’s not as if they had to cap the power to not step into the next territory, kind of like how Porsche has to do that with the Cayman -> 911. Tire size could have easily been increased at a very small cost if any and greatly helped grip/performance out of the box.
The tires are small on purpose for safety reasons. All manufacturers purposely make sports car under steer for this reason. They don't want the amateur spinning the car into a tree. It's easily remedied.
Mobile 1 Full Synthetic 5W30. Doesn’t matter what brand or weight you use, same result. Only true fix is the auxiliary oil cooler or run when the temps are cooler.
I’m not sure I’m understanding what you’re saying. Yes, the rear seats are cramped. A 350Z is a 2 seater with no back seat and I’m unsure about your last sentence.
@@W_F_CZ dudd get out of here itd worse than most coupes. Im 186cm and i was crushed in the back seat person infront has normal position for driving theyre like 175cm or so. 3 series of same years is small too but fits normal adults very easily. This does not.
@@ISFASTER Don't get me wrong it's a great car But it is what it is a Lexus IS with A V8 in it You have to make a car track ready in the after market very few cars are born track ready
You do realize the F brand was developed on a race track right? It has track capabilities and should have had some of my identified issues fixed before release. If this was an IS250/350 you would have a point...
@@ISFASTER waaaaay better than new isf cluster I like the old isf cluster though am not creating an argument just people have different taste why lexus had to pud that big rpm and small mph doesnt have any sense to me
If I’m the only one with this issue then why would Lexus add a secondary oil cooler to the RCF and GSF as well as at least 2 different aftermarket companies create a solution to the oil temperature issues the ISF experiences? For only the one ISF owner that’s experienced high temps?
ISFASTER someone mentioned that before. I took my car to Lexus and 2 master techs said it was the drivers side mechanical fuel pump. I even made a post on club Lexus and most people said it was normal. There’s a video on my channel, check it out. I noticed the noise after getting an oil change and oil filter change.
1 I Agree with ISFaster. Cracked headers. I had a master tech change my oil. Needless to say he thought this was a V6. He had no clue it was a V8. I got a low oil engine light and was really pissed. I had to babysit since then and watch them pour my 9.8 quarts of oil. Pathetic.
Yikes. That’s sad that a master tech had no idea the F has a V8. I always check my oil level after service and the mechanics at Lexus haven’t let me down.
I think the ticking from the fuel pump is normal. If you hear the ticking upon cold start and it goes away as the car warms up then I think that would be a cracked header.
Worried about your car’s oil going too Hot. Move out of that shithole state. Dude Lexus sold it as a daily car NOT a track car daily driven. LOL. Lexus have to comply with EPA that’s why the exhaust are the way this.
Have you ever looked at the stock system vs an aftermarket system? If so then you would see all the crimps and terrible angles the exhaust gases have to pass through. Lexus could have still passed EPA standards with catalytic converters in place and extracted more power.
What I hate the most about ISF is I don't have in my garage 😁👍
🤣🤣🤣

Yeah im in NC so we dont get the heat yall do in Cali, I havent tracked my F yet. I use my FRS for track duty.
Nice. Any plans to track your ISF?
@@ISFASTER yeah eventually. I need wheels/tires/track pads before I go. And looks like I need an oil cooler too.
Great to hear! Always great to hear/see other F cars on track. It’s almost like seeing a unicorn! Try it without the oil cooler first and see how she does in your climate and tracks.
My isF has bubbles in the coolant tank but there’s no overheat u think it’s the valley plate?

Not one a stock setup suspension with a 2012 stock wheel and 285 wide tires.
"This car sounds NASTY" LOL!
😁😎😂
Not just hate but constructive criticism included, well done
Thank you!
Can't you get new rims for wider tires? If it'll fit I guess
If you don’t mind me asking what is the profile on your tires 45?
Very educational, thanks for posting this! Looking forward to more videos. +1 subscriber!
Glad to hear you found it useful. Thanks!
I hate the stock brakes squeaking during normal use. It drives me nuts in stop and go traffic
Change out the pads. I switched to Project Mu NS400 pads and they feel the same as the stock pads, hardly any brake dust and are silent.
@@ISFASTER is it the pads ? I thought my front pads and rotors were the cause, less than 500 since i replaced them with oem and its squeaking again.
More than likely it’s the pad. I hate hearing that sound during normal street driving too. My track pads squeal but have a lot better bite and heat resistance so it’s a trade off.
I run Auto zone pads with Raybestos rotors since I don't race my ISF and they don't squeak at all.
@@josej4169 i just got autozone pads, (brembo) and new rotors too. :-(
Things I hate about the Lexus ISF:
1) I don't have one

Cool videos man. I have a 2012 ISF too. You mentioned you upgraded to wider tires...but also had new springs. You think there would be any fitment issues with out the new springs? I wouldn't think so... What's the aspect ratio of your front and backs? Thinking about upgrading my tires as well.
Never mind...saw your tire video. Thanks!
Glad you found that. Definitely upgrade those stock sized tires!
If an ISF owner does not take the vehicle to the track will there still be potential issues with the overheating of the oil?
Probably not unless you’re driving somewhere extremely hot doing track like driving.
I agree with you on the tires. IS350 gets 225/45, I hated it so I put 235 instead. I can't see IS-F with 225 upfront. Idk what they were thinking.
Yup, I would love to speak with whoever was in charge of tires selection to try and figure out their rational for the tires that were chosen.
Is that 255 285 tyre set up fit on factory wheels ??? Or need upgrade aftermarket wheels . Thanks
It works with the 2012+ year stock wheels.
what is your wheel size?
I drive my ISF in the Arizona heat and my oil temp has never moved or gotten hot.
Good video! Your exhaust sounds good. Will your exhaust pass emissions???
Thanks. It did last year. 😎😎😎
@@ISFASTER That's good to hear. Do you believe the IS350 has a restriction in the exhaust?? Do you have any drone?? I'm thinking about going with Xforce or Tannbe
Not too sure about the IS350. I will get a slight drone in 8th gear going up a gradual hill like on a freeway but can easily be fixed by shifting down and punching it. 😁😁😁

Nice I like that you picked out good points for these cars that are a bit of a conflict but it's still a nice car.
Overall still a good car! No car is perfect.
@@ISFASTER yea I wish the is did have a bit more leg room. Imma make one about my avalon
Probably my biggest gripe with this car is it doesn't have a good sport automatic mode. It's pretty obvious the trans logic is to get in as high a gear as fast as possible.

That’s about the only thing they’re good for, breaking the back end loose to hoon!
Good video.. I like how your front caliper decals have yellowed from heating those brakes up lol
Thanks! I’ve definitely gotten them pretty hot, it’s actually the stock paint and not a decal.
You’re right, my mistake..
What’s the biggest tire setup you can put on an IS350?
Best to check with someone who owns an IS350. 😁
It would be the same tbh... same chassis and sub chassis.
If the holes on the drilled rotors was chamferd, it may have helped with presenting the cracks.
Excellent analysis
With all due respect most people might not race this car, and if you wanting a 3rd seat at the back then IS350, ISF is desiged for the enthusiast.
They should! 😁😎👍🏻
Lack of camber is the part that drives me nuts. My SC400 has adjustable camber. Not too crazy but enough. Crazy to see that they didn't give us the option with the ISF. Those are some really important mods!
Yup, I also wish there was some factory adjustability for that.
So to sum up as I see it: not the ideal car for track in stock form but a hell of a nice car to drive and enjoy on day to day basis.
It’s a great daily driver. As long as it’s a cooler track day and you’ve put some better/wider rubber on then you’ll have a good time on track.
Great video for future buyer.
👍🏻👍🏻👍🏻
What kind of driving gets your car overheated? are you tracking? Mine never budges over middle unless its ridiculous situations
Did you watch the video?
@@ISFASTER yes.
On a road course, 80+ degrees outside, after 5-6 hot laps...
You did not watch the video sir lol
Which slotted rotors did you get?
Brakenetic - there are very few options for the Lexus ISF that don't use drilled rotors and that aren't 2-piece rotors.
@@ISFASTER Which pads did you go with?
I’ve been running Project Mu pads for nearly 2 years now.
I have the borla catback. It sounds similar to yours.
Yup, they do sound close but are distinctively different.
more vlogs please!
I'll try and give the people what they want!
Yo he's being a princess about it.. the car is amazing, any car you get can be better and modded differently.
The tires arent as thin as the 245 all around on the Challenger Scat Packs lol
That’s just pathetic that they would put such skinny tires on a car with nearly 500 horsepower and torque. 🤦🏻♂️🤦🏻♂️🤦🏻♂️
I have an ISF since 2012 and i live in California and never had oil temperature high.
Do you run your car on road courses?
When and How much did you guys pay for your ISF? Also how many miles? Lastly What year do you guys have? I’m a 19 year old and I’m thinking of buying a isf by the time I’m 21
I thought it was my data cutting out lol
🤪🤪🤪
225s?! Bahaha, what were they thinking! My ‘98 GS stocks 225s.
Yeah, an absolute joke!
My Quad ( 2006 Canam outlander 800) has 255s in the rear and 205s in the front..
Cool
And open diff on earlier models
I think the main issue is Lexus really didn’t make these cars to be sports cars alone like a mustang are camaro they still tend to lean toward the luxury and reliability side of things, maybe the RCF are the GSF you get better performances but your now talking about $40,000 to 50,000 grand
Performance isn’t much better if at all with the RCF and GSF. Definitely nicer interiors though.

Agreed. Shame they released it knowing it would overheat and never fixing the issue throughout the 7 year production run. 🤦🏻♂️🤦🏻♂️🤦🏻♂️
Late response, but tire size and horsepower cap is due to price point.
Toyota/lexus =conservative company.
No doubt Toyota/Lexus is conservative, especially with change. At the time of release of the ISF they had no performance vehicle classed above it in the Lexus lineup so it’s not as if they had to cap the power to not step into the next territory, kind of like how Porsche has to do that with the Cayman -> 911.

Fortunately, once a tune, tires, etc are addressed, the F vehicles become amazing!

I picked 5 things, these were them. The overall pros out-weighed the cons. 🤷🏻♂️😁
Great video man , my gs460 sounds exactly like ur ISF, i read somewhere that the ISF headers will fit my car , u should get them
Thanks. Regarding the headers, I’ve never heard/read that anywhere. I’ll be keeping the stock headers for now. 😁
The tires are small on purpose for safety reasons. All manufacturers purposely make sports car under steer for this reason. They don't want the amateur spinning the car into a tree. It's easily remedied.

Wrong, several ISF owners I know have this issue. What ambient temps are you running your car on track? Also, maybe you’re driving style is different.
