Excellent brake system upgrade. (especially for the track)
I had Stop Tech's 355mm front and rear BBK on my E46 M3 for four years.
They never disappointed me once.
*: You are wasting your money going with a 365mm
Brembo BBK. (front)
You know you want the increased thermal capacity
(and superior braking leverage) of the larger 380mm steel friction surface.
Just buy the 380mm
BBK front and
rear. I can recommend a set of high quality 18" track wheels
that are guaranteed to fit over them without spacers. (with the proper clearances)
PM me for details, so we don't contaminate rldzhao's brake thread.
