Question for 323 Owners running 330 Brakes

Hello - I have a questions for owners of 323s that have installed the 330 front brakes.

Did you change the master cyliner? I noticed the part numbers are different for the 323 and the 330 on pre 9/2000 cars. Mine is a 5/2000, 323 and I am thinking about swapping to 330 calipers. Wanted to know if I also need to switch out the master cylinder.

Thanks in advance for your comments,
Mike

Was wondering if you knew the what the differences are between the two different parts - for instance, do you know the if the master cylinder piston diameters are the same?

Are you running the 330i front calipers on you car?

Did you also change the rears calipers or did you leave the rears stock?

Thanks in Advance for your replies,
Mike

i swapped to 330i front and rear rotors/calipers on my car and did not change the master cylinder. I'm not sure if I apply here though (I have a 328i), too lazy to check realoem right now

Do not change it, your 323 master cyl. will clamp the 330 brakes just fine. My 328 master cyl. works like OEM on the 330 brakes.
