MMR Performance 2-Piece Rear Brake Rotors - Pair (370x24mm) - BMW G8X M2 M3 M4

Product Details

MMR Performance’s upgraded brake rotors are engineered as a direct replacement for your OEM discs, offering a superior braking experience. Designed as a two-piece floating system with dedicated left- and right-hand configurations, these rotors are lighter than stock while featuring larger directional cooling vanes to enhance performance, even pad wear, and heat dissipation.

The 370mm x 24mm floating rear discs pair seamlessly with MMR's front replacements, ensuring balanced braking power with matching grooves and efficiency. The floating design allows for controlled expansion under heat, preventing the warping and cracking issues that plague single-piece discs. As a result, MMR rotors last significantly longer than factory alternatives.

Precision-engineered from high-quality materials, the center hat is crafted from 6061-T6 aircraft-grade aluminum, while the rotors are made from a proprietary metal alloy built to endure extreme temperatures. A set of 72 directional vanes actively draws cool air through the rotor, maximizing heat dissipation. Unlike conventional OEM discs, MMR’s left- and right-hand design optimizes airflow for enhanced cooling and braking consistency.

Because MMR discs manage heat so efficiently, standard OEM brake pads perform exceptionally well under daily and spirited driving conditions. For track use, a high-performance pad upgrade is recommended, but our rotors are fully compatible with both OEM and aftermarket pad options, ensuring versatility and reliability.
