Brake Disc/Rotor Set (Cross-Drilled Floating) - Rear

These are the correct factory-style rear brake rotors for the BMW E9x M3 and BMW E82 1M, matching the original two-piece floating design BMW specified from new, with an aluminium hub and separate high-carbon friction ring.

Manufactured in Europe by a specialist brake rotor producer and built to OE standards, these rotors are supplied to us in plain white boxes, letting you enjoy genuine European braking quality without paying for the branding or dealer markup.

The rear brakes on the M3 and 1M play a critical role in vehicle stability, balance and traction under hard braking and corner entry. The floating two-piece design allows the friction ring to expand independently from the aluminium hat as temperatures rise, helping maintain consistent braking behaviour and reducing stress through the hub. The aluminium hat also lowers unsprung weight, contributing to the sharp chassis response these cars are known for.

The high-carbon friction ring features a cross-drilled pattern that helps clear water and gases from the pad surface while also giving the brakes the purposeful motorsport look these M cars deserve. More importantly, the metallurgy is tuned for excellent thermal stability, smooth modulation and long service life under aggressive use.

These rotors are precision machined and balanced to ensure smooth, vibration-free braking and bolt straight on with factory calipers and high-quality European brake pads, preserving the braking balance BMW engineered into these performance platforms.

If you’re refreshing the rear brakes on your M3 or 1M, these OEM Supplier two-piece rotors deliver the correct design, feel and durability — without paying inflated dealer pricing.
