Brembo Front Brake Rotor for BMW 2-Series/3-Series/4-Series (2012–2021) (09.9793.21)

This Brembo Front Brake Rotor (part number 09.9793.21) is the rotating disc the pads bite into, the part doing the real work of turning kinetic energy into heat under hard braking. In MotoGP, Brembo has been the exclusive brake supplier to every team for years running, with over 600 victories in the premier class since 1976.

Brembo's UV-coated rotors are built as a direct OE-equivalent replacement, with high-carbon iron used where applicable to control noise and resist thermal cracking. Match this part to your application using the fitment table below — Brembo's range covers exact OE positions, and getting the right one matters as much as the brand.
