Brembo Front Brake Rotor for BMW Z4 (2009–2016)

This is a Brembo front brake rotor (part number 09.R121.11) — the rotating disc the pads bite into, the part doing the real work of turning kinetic energy into heat under hard braking. Brembo introduced the first carbon brake discs and the first 4-piston radial caliper in Formula 1, technology that filtered down into the street parts on this car.

Brembo casts its rotors from high-carbon iron for better heat dissipation, the same metallurgy approach it uses across OE and motorsport programs. 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.
