This Brembo Front Brake Rotor (part number 09.A621.31) is the rotating disc the pads bite into, the part doing the real work of turning kinetic energy into heat under hard braking. Across motorsport, Brembo and its Group brands have now passed 1,000 world titles since 1975 — Formula 1, MotoGP, WEC, IMSA, and more.

Brembo machines its rotors to tight runout tolerances and uses Pillar Venting Technology on many applications to pull heat out of the disc faster. 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.
