You can also get the Z4MC BMW Motorsport style widebody via Flossmann auto design or KK Automobile but fitment seems to be for race car only if you see what I mean...

Thank you
CF. Although the proto first pull was FG.

It certainly can be core re-enforced to handle wing pressure down-force. But this adds weight of course.

A fully dedicated track car should really have a through hatch mount cut in. And perhaps a Zuess fastened lid rather than a fully functional bolt-on hatch.

the oem M bumper looks much better than the one on the aero coupe.

at least imo.

335 would be insane, that's more than some very capable cars:

GT-R
255/285 on 9.5/10.5" rims

911 Turbo S:
235/305

You'd probably want to keep the 30mm stagger between front and rear or you'd get a ton of understeer. Most track guys reduce this stagger a bit, terrytl runs 255/265, crfine runs 255/275.

Some options might be:

255/40 +0.23%
285/35 -0.68%

265/40 +1.44%
295/35 +0.38%

285/35 -0.45%
305/35 +1.44%

You'd have to have either a turbo or VT2+ to justify it though.

both cars you mentioned are AWD...

a powerful RWD car needs more tire in the back, unless they're running something really sticky.

My long term plans are 500 to 600rwhp, so eventually I'd love to run 305 in the back, and keep the 265 I have in the front at -2.5* camber

I'm doing OK with re-11s in 265 in the back for now though, when the tires warm up.


Anyway, back on topic, I though the TC Klein kit was 1" wider in the back that stock, can anyone confirm?
