Designed for owners who push their G8X M-car on aggressive backroad runs and occasional track-day use, but still daily-drive the car and need pads that work from cold without compromise.\u003c\/p\u003e\n\u003cp\u003eThe compound runs at a 0.42μ friction coefficient across the 450°C–650°C operating window. Full braking force is available from cold, no warm-up period required. Through repeated heavy braking the compound maintains near-zero fade and consistent friction characteristics, giving a progressive, predictable pedal feel under load. Slotted and chamfered construction keeps daily-driving NVH low and braking smooth.\u003c\/p\u003e\n\u003cp\u003eECE-R90 certification covers all the criteria required for road legality and insurance compliance in the UK and EU. Bedding-in happens naturally over the first 100–200 miles of normal urban driving, no aggressive bedding procedure required, just install and drive.\u003c\/p\u003e\n\u003cp\u003eFor the cleanest installation, pair this rear set with MMR27-1601-F front pads and MMX 2-Piece Floating Rear Rotors (MMR30-1602-R) for a complete G8X iron-brake refresh.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCompound: MMX RP650: medium aramid-fibre formulation (same family as front)\u003c\/li\u003e\n\u003cli\u003eFriction coefficient: 0.42μ across 450°C–650°C\u003c\/li\u003e\n\u003cli\u003eECE-R90 approved: public highway legal\u003c\/li\u003e\n\u003cli\u003eExcellent cold bite: full braking force from cold, no warm-up required\u003c\/li\u003e\n\u003cli\u003eNear-zero fade under sustained high-temperature use\u003c\/li\u003e\n\u003cli\u003eSKU: MMR27-1602-R\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× set of 4 rear brake pads (one vehicle, rear axle)\u003c\/li\u003e\n\u003cli\u003ePad shims (pre-shimmed)\u003c\/li\u003e\n\u003cli\u003eBrake fluid, lubricant, and fitting accessories not included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBMW M2 (G87)\u003c\/li\u003e\n\u003cli\u003eBMW M3 (G80 \/ G81)\u003c\/li\u003e\n\u003cli\u003eBMW M4 (G82 \/ G83)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eRelated Products\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMMX RP650 Performance Front Brake Pads G8X\u003c\/li\u003e\n\u003cli\u003eMMX 2-Piece 370mm Floating Rear Rotor G8X\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for G8X iron-brake cars.\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eCarbon Ceramic Brake (CCB) cars require a separate CCB-specific rear pad\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e(e.g., Pagid RSL29, MMR27-1610-R).
