Thanks for sharing your experience. Your video inspired me to do the same on my now 650whp m240 xdrive. This was not an easy process and took quite a bit of customization by Regal Motorsports to make this work, but it’s one of the best mods I’ve done to date!
Hello again,it't been 3 weeks since we had this conversation,and I had my 328 modified during the time. I took your advise to stick with the FTP pipes, and got myself a intercooler which is local made and copied from Wagner EVO 2. And I put a Awron gauge to check the IAT. With the boost peak @1.58bar,and IAT 15 - 25 celcius higher than ambient,I guess everything related to the intake and turbo is fine. Now the engine is having a little turbo lag, but it is ok for me. And I even had a oil catch can installed😊. Another thing is the Eibach ARB, I had the vender installed it for me, but had to do alignment myself. With these ARB, the car handling very well on the street and twitchy roads, I think that is what I aimed for, I even feel the suspension rides more freely after I had the endlinks aligned myself, and that is what I learned most from your video. But I do noticed that the ARB lever arms are not leveled from left to right both front and rear, and that is after I zero out the ARB preload. The front is a bit lower on the left, and the rear is a bit higher on the rear. Such causes the different endlink lengths. There was a tech guy from a local racing shop point out that the endlink must be exactly the same lengths for ARB to function right, and I don't feel any unbalance during steering or turns, so I insist what is more important is to zero out the preload, and he laught at me😂. Had me began to concern if the ARB was bend during shipment, but I took them our of box brand new, even if it was bend, no way the F&R bend at the same time. So I did a little research, found out there is no one understanding the ARB and the endlinks right at chinese net, they don't even know about preload, what a pity of their passion for auto modification. After a lot of google for the answer, I found two guys @miata fourm back in 2008, had montioned the endlinks could be different lengths to zero out the preload, probably the driver's side will be longer. And that is exactly what am I experiencing right now. So it worries me no more. And now I'm looking for LSD as final modification for my 328. One more thing, I'm stick with the "flat ride" theory that I learned from you, practiced in a drifting game on mobile which names Carx Drifting Racing 2, and some significantly benefits shows on my tunes, very happy with it.😁 Thank you😁👍
Wow, you've made quite a bit of progress, congrats on the mods! Good on you for confirming the research and not just taking the shop's word for it. I find it pretty funny how you used a racing game to test/prove flat ride works. That's innovative!
@@FaRKle0079 I doubted the endlinks have to be the same lengths cause they don't even know about preload. I believed in "flat ride" cause the natural frequencies curve shows the front and rear of the suspension will be settle at almost the same time, that helps a lot of driving commfort and handling druing extremely driving condition. So there it goes the "flat ride", the golden key of street car tuning. I think the natural frequencies helps alot in track driving, simply use them for oversteer or understeer specs. And tune the dampers to have a smooth weight transfer speed.
Hello, I'm planning to order an ATB from Diffsonline. I saw they send the pumpkin with the back cover separately (I assume with all bolts). Just wondering, do I need to purchase sealant to assemble it myself? Did you just send all parts to Vtmotorworks to let them handle everything? Thank you!
@@zqy6722 since I sent them a complete donor pumpkin they included the bolts it came with when sent back. You'll want to have some rtv/gasket maker for reassembly of the cover. I just had VT Motorworks do all that since they were handling the install anyways.
Hello, Thank you for sharing this video. Extremely helpful. Just wondering did you change the gear ratio from the stock differential? I saw there are several ratio options in their website(+$1000 of cause).
I have a 435i and my diff is making a howling noise when accelerating so now i am looking at wavetrac! This doesmt make noise in the inside of the car does it?
Do you have a serial number of the wavetrac LSD? I cannot find one that suit the 188LW diff of my 140i Xdrive. Did you preserve the 2.81 ratio of the stock one?
Your car should have the exact same rear diff as mine, so what I did you can do too. I still have my original diff if you're looking to buy one as a donor so you don't have extended downtime.
Nice video. Just wondering if you had to do any coding for the DSC system? I'm thinking specifically about the ADB function which applies the brakes to the inside slipping tire in a turn. I guess with an LSD this inside slippage is converted into mechanical grip but just wondering if this is a "plug and play" application. Thanks.
I have watched this video about 5 times now. Only question I have is, did you have the upgrade axles or even? Is there any actual upgrade for the F30X chassis ex? Drive
Just guessing, but I think the reason the end cover was not installed was so that you could see the Wavetrac inside for confirmation that it was actually installed.
Hey I love your videos, I have a question.. I have a 2014 bmw 335i xdrive running xDelete but I can’t rly get more power unless I go lsd.. would the wavetrac lsd work on my car or so there something I would have to do.
Yes you can have a wavetrac LSD installed into your diff (or buy a donor diff like I did so there's no downtime). 335i xDrive might even be able to use the M-Perf LSD meant for the 335i RWD.
@@FaRKle0079 I thought about that and wasn’t sure because tuner motor sort sells one for my car but only the rwd version so I wasn’t sure if it would mess my dsc or transmission since my diff is 3.15 ratio and the one lsd m performance is a 3.23 ratio.
In many cases a wheel might have been slipping with open diff, but is not slipping thanks to LSD. The feeling can be similar to torque vectoring: rather than peeling the inside wheel, the outer wheel receives that 'waste' torque instead, pushing the car into the corner. And slipping could still occur if you decided to push further (initiating a drift).
Hi, I have decided to do this with my 340i xDrive, I'll probably go with VAC motorsport instead of diffsonline since I prefer them, still gonna order the wavetrac unit tho. I do have a quick question about ordering tho, are there different lock up ratios you can choose from with wavetrac, or is it just one OTS unit?
I can drift perfectly w/ open differentials and xdrive using xdelete . You just need to know the right procedure so you dont damage something. I should make a video showing people
@@FaRKle0079 After driven my 328i for 120k kilometres,my stock suspention has gone, so I got OHLINS R&T installed six months ago,so far happy with it,even happier when I looked into your research. But there's still significantly body roll when I'm cornering at high speed, so I decided to have Eibach anti roll bar (which is 28mm in the front and 16mm in the rear) install this week to see for any difference. The LSD would be next step. I'm wondering why is Wavetrac LSD being able to offer some load and lock in a no load situation? I was told the torson LSD such as Quaife is not able to lock in a no load situation like one wheel in the air. And because I'm in china, getting a Wavetrac or a Quaife is way to expensive almost like 3000 dollars to get everything done without mentioning the long shipment. So it would going to be a custom Torsen LSD copied from Quaife at local for me, I guess, and that is about to cost 1200 dollars to get everything done. One more thing I'm wondering, did you happen to find any understeer while deceleration after installed the LSD? I don't have any experience with a LSD car, but I was told the lockup is good for power steering but it could be understeer while off throttle.
@@fujiki5507 Sounds like you've got some great mods! I'm not sure you need the rear bar since the Ohlins kit has pretty stiff rear springs. If you don't have to get it installed right away you might want to try just the front bar first. The Wavetrac LSD has internal plates with wavy surfaces that creates load on both sides under normal no-load conditions. This is why it can still bias under a one-wheel condition, and create bias under braking/deceleration, which is something other torsen differentials can't do (like Quaife). If you do get a Quaife, you shouldn't have any difference off throttle than you do now since it essentially acts as an open diff when off-throttle. The Wavetrac definitely stabilizes the rear when off-throttle, which was a bit surprising to me.
@@FaRKle0079 I've noticed what you had experencing with a stiff rear ARB on the track, got me worried since the OHLINS is pretty stiff on the rear.But my stock ARB bushings are running out,and I've already ordered the EIBACH kit,so I guess I will have to install it right away within the shop. A street car for daily driving is what am I intend to build,I do not put the throttle too hard on the street,but love to drive it around 5000 revs,and I like it with a little slide on the rear,so I'm guessing the stiff rear ARB would be ok for me to try it out. Right now I've got a catless downpipe with everything else stock related to the engine,not planning on add more power,but I would like to modify the intake pipes and intercooler for reliability(not sure if that's going to be the case),can I have your advice? It's good to know that Wavetrac had make in more like a 1.5WAY LSD,it's definitely the best choice for F3X chassis,I will figure out to get myself one of these.
@@FaRKle0079 i waited one year for mine to be built .............. after they recieved the core. not sure what the deal was but i got it at a good time so im happy.

I just got an F31 and I just discovered your wealth of knowledge and generosity in sharing it with the community. Thank you very much!
I always wanted to see a road test of the wavtrac under normal driving conditions. I am sold.

Hello, Thank you for sharing this video. Extremely helpful. Just wondering did you change the gear ratio from the stock differential? I saw there are several ratio options in their website(+$1000 of cause).
I kept the stock gear ratio since this is still a daily driver.
I have a 435i and my diff is making a howling noise when accelerating so now i am looking at wavetrac!
This doesmt make noise in the inside of the car does it?
There's zero noise from my wavetrac.
Do you have a serial number of the wavetrac LSD? I cannot find one that suit the 188LW diff of my 140i Xdrive.
Did you preserve the 2.81 ratio of the stock one?
How would this process differ for me and a 2020 M240i xDrive? Everywhere I've read says an LSD isn't compatible with it.
Your car should have the exact same rear diff as mine, so what I did you can do too.
I still have my original diff if you're looking to buy one as a donor so you don't have extended downtime.
Does it help putting the power down better on a xdrive 340i? My tires spins at launch xdrive on ps4s
Yes, it'll help with, "One wheel peel" since the amount of slip between wheels is limited.
Nice video. Just wondering if you had to do any coding for the DSC system? I'm thinking specifically about the ADB function which applies the brakes to the inside slipping tire in a turn.

For the F2x/F3x no coding is required. It's plug and play!
What coding is required if you have xdrive
I have watched this video about 5 times now. Only question I have is, did you have the upgrade axles or even? Is there any actual upgrade for the F30X chassis ex? Drive
I didn't change my axles at all. I just got new axle seals for the diff.
Just guessing, but I think the reason the end cover was not installed was so that you could see the Wavetrac inside for confirmation that it was actually installed.
Hrm, that could be!
hello! you have any idea if it is a similar option LSD for a 435d xdrive? can’t find anything on forums for 3.0 diesel with xdrive.
Wavetrac should have a version for the bigger 210mm ring gear in your 435d.

So can you drift like a rwd car when you switchoff the x drive?
Absolutely! LSD allows me to kick the rear out even in AWD mode.
What was the total cost to get the LSD with installation?
The diff was $2800, and installation was another couple hundred.
@@FaRKle0079 Nice thank you!
wait so this makes awd turn into rwd?
No, it just keeps xDrive in its rear biased (40/60) default mode more of the time.
Does this fit an f32?
Diffsonline can do the same conversion for your F32. The specific whole unit I have is the same for F32 435/440ix, but the RWD ones will be different.
The placebo effect is real
what BMW with 4 wheel drive where is this world going. :(
Going faster... Smh
Dude... unless your wheels are slipping you will not notice a difference with an lsd
it works whenever you have significant rotation speed difference between wheels, that doesn't mean they are slipping

If your wheels aren’t slipping you aren’t driving hard enough. Ya fat lipped taco.
have you never drifted? its not nearly as fun with an open diff

Good luck! Fantastic mod. If you were local (Bay Area) I'd say, "Buy my old diff to use as a donor" haha.
Any issues so far? Would this be safe with x-delete? Wanna drift around
No issues so far. It's been great! I ran my car in RWD mode for over half a year with this. You'd definitely be able to drift around.
