Few names carry more weight in braking than Brembo. Brembo has supplied Formula 1 since 1975, and in 2025 every single Grand Prix winner ran on Brembo or Brembo Group brakes. This front brake rotor (part number 09.D423.11) is the rotating disc the pads bite into, the part doing the real work of turning kinetic energy into heat under hard braking.
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.
