From what I could find the 128i master cylinder has 23/22mm bores while the 335i has 25/22mm bores.
I am NOT changing master cylinder, as I wish to maintain my brake bias. If the pedal travel is too long, I may consider a change.

My bigger concern might become getting Corner Brake Control coded out. I used to race a 328i that was being prepared for IMSA ST, but was on stock ABS, and the CBC was a significant problem.
