I love how you went from "why am I doing this" to "fuck it we're doing it baby!" in a matter of 4 posts. I respect that. Start a separate build thread with pics if you haven't already. Sounds like a dope car.

Went with the Wavetrac (complete 3.08 pumpkin from Diffsonline) and retrofitted a 650i finned diff cover. Did the install last weekend on ramps in the garage. Pretty straight forward but the 50mm driveshaft nut was a gigantic pain in the ass.

Phenomenal improvement but am still breaking it in. Should have done this 8 years ago when I got the car.

Shame on BMW for not making this a factory option.

Yeah they didn't want it to compete with the m3 which makes sense. At least there are plenty of diff options now.

Glad i found this thread, as I've started on track upgrades for 2008 N54 335i generally following https://grassrootsmotorsports.com/ar...ble-track-car/

I've tackled the "front" so far with m3 control arms, sway bar, fixed 2.5 camber plates to fit square 18x9.5" ET35 with 265/35.
Upgraded intercooler, downpipes, chargipe as a side project.

I hope I only need to install the rear sway bar and "race" align the car for this season.

Need to plan the "rear" project and there is good info here. I want an LSD next.

as someone who is on the road to getting their e90 drift spec, i think it’s because of the complexity. You have to think about a lot of things, flammable materials (windshield wiper fluid delete), ac delete (have to relocate pulley) there’s just a lot. It’s also super prone to breaking

I am on my way to building e90 328i track toy as well. Picked it up for next to nothing with 106k with a dead clutch.

So far this is a list of things I am planning to do since I have some of these parts laying around from past cars.

- Euro Airbox
- Silicone elbow
- N54 oil filter housing with thermostat and oil cooler
- 3.73 diff from an auto
- Tuner fixed camber plates
- Bilstein PSS10 coilovers
- TRmotorsports C4 with 245/40/17 RS4 tires
- Remove CDV during clutch replacement
- Pair of Recaro SRD seats up front

Debating on which brake pads and likely using ATE200 for brake fluid.

Headers and Milvs later on down the road if I get that deep into it.

Simple enough build to just have fun with it.

Pretty soon this thread will need to be renamed "Why are there so many track cars?)

Yeah I think the manual e9X and 1 series platform has potential to be the next track toy car for people. Similar to what the non-M e46 is becoming.
