MMX 370mm Rear 2-Piece Floating Brake Discs for BMW G8x

The MMX 370mm Rear 2-Piece Floating Discs are a direct-fit upgrade for the OEM rear brake discs on the BMW G8x M3 and M4, supplied as a matched left/right pair.

Each disc uses a two-piece floating design that's lighter than the factory rotor, paired with larger, more efficient directional cooling vanes for more consistent braking performance, better pad wear and improved heat management under repeated hard use.

• 370mm x 24mm left and right-handed discs, sold as a pair
• Two-piece floating construction, lighter than OEM
• Larger directional cooling vanes for improved heat management
• Matching 2-piece front discs available separately
