2/ i am guessing that maybe you do circuit racing since you went with multiple calipers front and rear. is there a huge difference??
i ask becauese on the street, my stock brakes seem pretty good.
if you are tracking your 335, how did the stock brakes hold up before you changed out your calipers?
a friend/track instructor who tracks quite a bit with many different cars...including Porsche, corvette...thought the 335i brakes were very good for track. i thought they were good but I can't compare against other.
