Designed specifically for BMW F8x platforms, these performance rear discs run up to 30 percent cooler than OE and increase cooling efficiency by up to 30 percent for stronger, more consistent stopping power on fast road and track day use.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Built to match the MMX front replacement discs, they feature matching grooves and matching performance for a balanced brake upgrade front to rear. The two-piece floating design allows the disc ring and aluminium hat to expand radially and axially under heat, significantly reducing the risk of warping and cracking often seen on single-piece discs. Thanks to this efficient construction, MMX discs last considerably longer than factory discs while delivering improved pedal feel and reduced fade.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eWhy choose MMX 370mm rear brake discs for BMW F8x M cars\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e370mm x 24mm 2-piece floating rear discs and rotors for BMW F80 M3, F82 M4, F83 M4, F87 M2\u003c\/li\u003e\n    \u003cli\u003eUp to 30 percent cooler than OE and up to 30 percent more cooling efficiency\u003c\/li\u003e\n    \u003cli\u003e36 directionally curved vanes that pump air through the rotor for rapid heat dissipation\u003c\/li\u003e\n    \u003cli\u003eLeft and right-hand specific rotors to optimise airflow and cooling\u003c\/li\u003e\n    \u003cli\u003eGrooved friction surface increases initial bite, improves brake feel and deglazes pads\u003c\/li\u003e\n    \u003cli\u003e6061-T6 aircraft-spec aluminium centre hat for strength and thermal stability\u003c\/li\u003e\n    \u003cli\u003eProprietary rotor alloy engineered to withstand extreme braking temperatures and hold form\u003c\/li\u003e\n    \u003cli\u003eDirect rear replacement for OE discs, compatible with factory calipers on F8x models\u003c\/li\u003e\n    \u003cli\u003eUse with OEM pads or aftermarket performance pads for fast road and track\u003c\/li\u003e\n    \u003cli\u003eDesigned to pair with MMX front discs for a complete performance brake upgrade\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003ePerformance benefits\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eImproved cooling and reduced fade during spirited driving and track days\u003c\/li\u003e\n    \u003cli\u003eMore consistent pedal feel and stopping performance lap after lap\u003c\/li\u003e\n    \u003cli\u003eReduced risk of warping and cracking compared to single-piece discs\u003c\/li\u003e\n    \u003cli\u003eLonger disc life in real-world conditions\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eHow the cooling works\u003c\/h3\u003e\n  \u003cp\u003e\n    Internal directional vanes draw cool air from the centre of the disc and force it outward as the rotor turns. This pumping action rapidly moves heat away from the friction surface. Unlike OEM one-direction discs, these MMX rotors are handed left and right to maximise airflow and keep temperatures stable for consistent braking performance.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eFitment and compatibility\u003c\/h3\u003e\n  \u003cp\u003e\n    BMW F8x platform rear brake discs and rotors, including:\n  \u003c\/p\u003e\n  \u003cul\u003e\n    \u003cli\u003eBMW F80 M3\u003c\/li\u003e\n    \u003cli\u003eBMW F82 M4\u003c\/li\u003e\n    \u003cli\u003eBMW F83 M4 Convertible\u003c\/li\u003e\n    \u003cli\u003eBMW F87 M2 and M2 Competition\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003cp\u003e\n    Please check your existing rear disc size is 370mm x 24mm before ordering if unsure.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eFitting and support\u003c\/h3\u003e\n  \u003cp\u003e\n    Professional fitting recommended.
