zboot's 328ti Project - A couple years early

[Bluebimma]

I havent decided to run the booster, so just the brakes at the moment. As far as 15s go, e34 and e39 rims come in 15s and 16s. The m3 rotor is 328mm iirc, the e34 is 302mm, and the e39 is like 322mm or something like that, so you could use those rims with m3 brakes too.
