EBCs fully floating 2-piece brake discs combined with our track focused Bluestuff pads represents the ultimate braking upgrade for high powered vehicles driven fast on road or frequently driven on track. EBCs Bluestuff material is R90 approved and thus totally road legal yet has a higher emphasis placed on on-track performance, making it the perfect choice for customers who want to keep their car road-legal but demand excellent performance when they get to the racetrack. Bluestuff has a high cold friction level, excellent pedal feel; and boasts a higher fade resistance over EBCs popular Yellowstuff compound. EBC Racings 2pc fully-floating brake discs are engineered from the finest materials without compromise, resulting in one of the highest quality 2-piece brake discs available on todays marketplace. These discs are equally at home on the road or at the race track. Outer friction rings are cast from high-carbon G3500 disc alloy, giving excellent wear properties and crack resistance even after heavy on-track use. EBCs patented stainless steel SD-Drive bobbins allow the braking ring to float freely and independently of the centre bell, reducing stresses and eliminating the chance of warping, whilst each bobbin location features an anti-rattle clip for totally silent operation. All discs feature 48 curved vanes and are handed to each side of the car allowing effective heat dissipation. EBC 2-piece discs often offer a weight saving over OEM parts, helping to reduce rotational un-sprung mass that has a positive effect on driving dynamics. Additionally, when the disc eventually becomes worn, the hub can be retained replacing only the outer friction ring which reduces long term operating costs.
