Designed and tested by MMX as a direct replacement for the OEM iron front disc, this is a true two-piece floating rotor (left- and right-handed specific) built to drop the OEM rotor's heat-induced limitations without any caliper or hub modification.\u003c\/p\u003e\n\n\u003cp\u003eEach rotor pairs a proprietary high-carbon iron ring with a CNC-machined 6061-T6 aircraft-specification aluminium hat, connected by a floating bobbin system. That floating mount allows full radial and axial thermal expansion as the rotor heats, eliminating the most common failure mode of single-piece OEM discs (warping and surface cracking under repeated heavy braking). The aluminium hat is meaningfully lighter than the OEM cast hub, reducing unsprung and rotational mass at the front axle where it matters most for steering response and ride control.\u003c\/p\u003e\n\n\u003cp\u003eThe friction face is laid out with 72 directionally curved cooling vanes that act as a centrifugal pump as the rotor spins, drawing air through the center of the disc and out through the friction ring. MMX states the assembly runs up to 30% cooler than the OEM disc, which translates directly into less fade on track, more consistent pad release behavior, and longer rotor life across track-day cycles. MMX's signature directional grooves on the friction surface improve initial bite and clear pad gases and debris from the pad face.\u003c\/p\u003e\n\n\u003cp\u003eThis rotor uses the OEM 6-piston front caliper that came on F80 M3, F82\/F83 M4, and the original N55-engined F87 M2, and it accepts OEM or upgraded MMX RP650 \/ RP750 brake pads. It is not compatible with the F87 M2 Competition (silver caliper variant) and is not compatible with the M Carbon Ceramic Brake (CCB) package.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDiameter × thickness: 380mm × 30mm\u003c\/li\u003e\n  \u003cli\u003eTrue 2-piece floating construction with floating bobbin mounting system\u003c\/li\u003e\n  \u003cli\u003eProprietary high-carbon iron rotor ring with directional groove pattern\u003c\/li\u003e\n  \u003cli\u003e6061-T6 aircraft-specification aluminium hat (CNC-machined, anodised)\u003c\/li\u003e\n  \u003cli\u003e72 directionally curved internal cooling vanes\u003c\/li\u003e\n  \u003cli\u003eSKU: MMR30-1001F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e1× Left-hand 380mm × 30mm 2-piece floating rotor (with floating bobbins pre-installed)\u003c\/li\u003e\n  \u003cli\u003e1× Right-hand 380mm × 30mm 2-piece floating rotor (with floating bobbins pre-installed)\u003c\/li\u003e\n  \u003cli\u003eBrake pads not included: sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/m2-f87\"\u003eBMW M2 (F87)\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/m3-f80\"\u003eBMW M3 (F80)\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/m4-f82-f83\"\u003eBMW M4 (F82 \/ F83)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eRelated Products\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/products\/mmx-performance-f8x-m2-m3-m4-2-piece-floating-rotor-set-rear-370x24mm\"\u003eMMX F8X 2-Piece Floating Rear Rotor Set 370×24mm\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/products\/mmr-performance-f8x-m2-m3-m4-rp650-performance-brake-pad-set-front\"\u003eMMX RP650 Performance Front Brake Pads F8X\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNOT compatible with F87 M2 Competition\u003c\/strong\u003e (silver-caliper variant).
