When developing these brake discs, the mission was to engineer the highest quality 2-piece brake discs possible.

These discs are manufactured from the finest materials and consequently are some of the highest quality 2-piece discs sold on the market at any price point. All outer friction rings are cast from a high-copper high-carbon G3500 disc alloy. The bells are precision machined from aerospace grade aluminium then hard anodised for great looks and excellent durability.

The cast iron outer ring 'floats' on EBC's patented SD-Drive technology bobbins, allowing the friction ring to expand and contract freely by up to 3mm when subjected to the extreme heat generated from hard braking.

All bobbins are machined from a single piece of stainless steel. This prevents unsightly corrosion and ensures the outer ring continues to float freely even after years of exposure to the elements. This means that EBC Racing's 2-piece floating discs offer a low maintenance solution that are at home on both the public roads and the race track. Each bobbin location also features an anti-rattle spring clip, meaning these discs are totally silent in operation and do not have the 'off brake disc rattle' that plagues many other full race 2-piece disc systems.

Upgrading to an EBC 2-piece disc will shave crucial kilogrammes off a vehicles un-sprung rotational mass, leading to sharper turn in, improved tyre road holding, better fuel economy and an increase to BHP at the wheels. Best of all, when the cast iron friction ring becomes worn after a period of use, the outer ring alone can be replaced, allowing the centre hub and stainless bobbins to be re-used, reducing long term running costs.

Fully Floating Two-Piece Disc

• EBC’s 370x24mm two-piece fully floating discs are a simple bolt-on upgrade that seamlessly replace the original ‘pin-drive’ brake discs without vehicle modification.
• Unlike the stock pin-drive discs which do not float, EBC’s SG2F fully floating rotor allows the outer cast-iron friction ring to expand freely with temperature, totally eliminating disc warping.
• Discs are grooved unlike the original rotors which are perforated. This allows the pad to vent without the holes becoming epicentres for disc 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 radiate 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 disc’s ability to radiate heat, increasing brake system endurance and prolonging the onset of brake fade.
• Bobbins are machined from stainless steel which cannot rust, ensuring the disc 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 disc 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.
