This is a Brembo rear brake rotor (part number 08.5366.21) — the rotating disc the pads bite into, the part doing the real work of turning kinetic energy into heat under hard braking. From Niki Lauda's 1975 title with Ferrari to Max Verstappen's recent championships, Brembo brakes have been on the car for nearly every era of F1 dominance.

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.
