Over the past 12 months, EBC Brakes has proudly been one of the first aftermarket companies to supply high-performance braking components for the new G8X-series BMW M3/M4 models.

With a range of brake pad compounds and fully-floating two-piece front rotors already available, the Northampton-based firm is now expanding on this range with the introduction of matching rear floating rotor for this acclaimed range of sports cars.

Research and development work for this component was performed alongside several vehicles and companies, including London-based R44 Performance and its G80 M3 Competition.

The result is a 370x24mm version of EBC's much-loved two-piece floating rotor that can be bolted directly on to the rear axle of all G8X-series M3 and M4 models (apart from those sporting optional carbon ceramic brakes), offering impressive braking performance and longevity, especially when driven hard on road and track. These are the perfect complement for the 380x36mm front discs already available.

With the new M3 and M4 already being hailed as one of the most rewarding driver cars on sale today, this upgrade is a valuable addition to the EBC Brakes Racing range.

Features:

• EBC's 370x24mm two-piece fully floating rotor are a simple bolt-on upgrade that seamlessly replace the original discs without vehicle modification.
• Unlike the OE rotors, EBC's SG2F fully floating rotor allows the outer cast-iron friction ring to expand freely with temperature, totally eliminating rotor warping.
• Rotors are grooved unlike the original rotors. This allows the pad to vent without the holes becoming epicentres for rotor cracking.
• Race-derived G3500-grade high-carbon cast iron is used for the friction rings. This high-quality metallurgy possesses greater crack resistance and an increased ability to conduct and then dissipate heat.
• Aluminium bells are machined from aerospace-grade aluminium and then hard anodised for longevity, whereas the stock brake rotors use uncoated cast aluminium bells.
• Cast iron friction rings feature 48 curved vanes and are handed for each side of the vehicle. This significantly improves the brake rotor's ability to dissipate heat, increasing brake system endurance and prolonging the onset of brake fade.
• Bobbins are machined from stainless steel which cannot rust, ensuring the rotor continues to float freely throughout its entire life cycle on the vehicle, even on road cars.
• Spring clips ensure totally silent operation and eliminate off-brake rotor rattle.
• Friction rings can be replaced individually after they have become worn, allowing the aluminium bell and stainless-steel bobbins to be re-used, leading to lower long-term operating costs.
• Now featuring the latest thermic black corrosion-resistant finish–the very latest in rust prevention.
