These high-quality, 345mm x 24mm front discs are designed as a direct replacement for your M-Sport factory originals, ensuring a hassle-free installation. Matching rear discs are also available for a complete upgrade. Oh, they're also public highway legal, R90 Approved. Supplied as a pair of high quality, direct replacement 345mm x 24mm rront discs/rotors. MMX Performance rront discs/rotors are the ultimate upgrade for your BMW F2x or F3x M-Sport brakes (blue calipers). Designed to directly replace the factory 345mm x 24mm discs, they feature MMX’s signature directional groove design for enhanced braking bite, improved debris clearance, and reduced distortion vibration during high-temperature track use. On the road, these directional grooves generate less noise compared to straight or curved groove designs and avoid the fatigue cracking often seen in drilled discs after repeated heat cycles. The two-piece construction consists of a high cast carbon rotor—a premium blend of high-quality steel and carbon that delivers a superior friction coefficient compared to standard steel rotors—mounted via a pin-drive system to a lightweight aluminum center bell/hat for optimal performance and durability. A matching pair of front MMX Performance discs/rotors are also available (MMR30-0501F); ideally we’d recommend fitting front and rear disc sets at the same time. Features Perfect for fast road & trackday use. High carbon brake rotor. Pin drive aluminium bell/hat. Zinc anti-corrosion coating on centre bell and outer lip. Public highway legal, R90 Approved. Matching front MMX Performance discs available. Quiet and smooth braking with MMX directional groove design. Additional Information To ensure long-lasting performance and maintain their sleek appearance, the discs feature a durable black zinc high-temperature coating on the center bell and outer lip. This protective layer offers excellent thermal resistance and guards against corrosion, keeping your hubs looking pristine for years to come. Say goodbye to unsightly rusted factory hubs once and for all!
