I'm in the process of upgrading to e46 325 300mm rotors in the front. I have a question.
If I read this thread correctly
http://318ti.org/forum/showthread.php?t=29763 The front calipers on:
e46 330i = 57mm
e36 m3 = 60mm
318ti = 54mm
Does anyone know what the stock piston size is on a e46 325i?
If I recall correctly going with a bigger front caliper piston makes the pedal squishier. So to do this correctly you'll need the m3 master cylinder.
Any help is appreciated.
