I traded my 2015 328i xDrive in for a new M3, so I'm selling off the performance parts. These brakes have only 4,000 miles on them and are still like new. BMW will even cover them under their new car warranty if your car is still within warranty range. This is the complete bolt on kit, nothing is needed. When purchasing from the dealer, the rear rotors aren't included which they don't tell you. New this setup is over $2,000.

Brembo high-performance 4-piston aluminum fixed caliper on the front axle and 2-piston aluminum fixed caliper on the rear axle. Improved thermal resistance thanks to larger, internally-ventilated, lightweight-construction sports brake discs. Dimpled and grooved brake discs also reduce water film build-up between the brake lining and the disc surface. Available in M Performance Red, Yellow or Orange – all with an M logo on the outside of the caliper. Dimpled and grooved, internally-ventilated lightweight brake disks with riveted aluminum hat measuring 370x30mm on the front axle and 345x24mm on the rear axle.
