What does it take to use the m3 master cylinder? I know the 25mm one from the 750's work but some people say they make the pedal too stiff. The m3 one is 23mm and realoem makes it look like the fittings are the same size for the brake lines. M10's. What all does it take to use the m3 master cylinder on a late model 325i? 1991 325i 5 spd
