To start with I'm using this as reference:
I am thinking of getting a set of ST40 calipers for my 2005 ZCP M3. I found a good deal on the set not designed for the ZCP car. So if I were to swap over to regular m3 rear calipers what would happen to my brake bias?
It looks like it would move rear 7% but I might be wrong.
Any help would be awesome. Thanks.
