If you have a 330i/Ci you can upgrade to the 13.5" E46 M3 CP brakes...

Here's how. You will need Competition Package rotors (left and right), Competition Package brake caliper carrier (x2), and a set of front pads made for the M3.

Competition Package 2 piece rotors:
34.11.2.282.445 (right)
34.11.2.282.446 (left)

Carrier:
34.11.2.282.619 (x2)

Pads you can source from wherever you like and use whatever compound suits you, as long as they're made for the M3. Reason why is the M3 rotors are 3mm thicker, so the pads need to be made slightly thinner to fit. If you have some wear on your OE pads already you may not even need new pads.

So far I've confirmed that the pads from an M3 fits the front 330i/Ci caliper and carrier (and leaves a small, 1.5mm gap on each side). The carrier designs are all the same. Total cost, not counting pads, comes to around $900 for new parts. It's a cheap(ish) way to do an intermediate upgrade to your stock brakes without spending $2,000+ for a true big brake kit. Depending on your use and application this might be a better route.

You can also source aftermarket rotors from RacingBrake that allow you to re-use the hub and just purchase new rotor discs:

I have a set for sale, brand new, only opened to inspect and take pictures, never used, never installed, for $360 ea ($720) total if anyone is interested. I don't check the PM here that often, so if you want to take a stab at these rotors, drop me a line at:

No, caliper HOUSING and mounting points are the same. Caliper PISTON sizes are different. You don't need a new caliper, your OE caliper housing will bolt right up to the new caliper carrier.

To upgrade to Competition size rotors, you need the caliper carrier, not the entire caliper. They run around $175ea from Pelican parts.
