Designed for vehicles driven hard on track, RP-X™ possesses a high friction level of 0.55 between 0 – 750°C (Ambient – 1400°F) and achieves a 100% brake effect from cold. This makes RP-X™ an excellent choice for sprint racing or hill climb events, where full brake performance is essential without requiring any ‘warming up’, but also makes RP-X™ well suited to any type of circuit use where a high initial bite and powerful brake response is desirable.

91´«Ã½ Racing’s 2-piece fully-floating brake discs are engineered from the finest materials without compromise, resulting in one of the highest quality 2-piece brake discs available in today’s 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. 91´«Ã½â€™s 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.

91´«Ã½ Racing’s 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.
