BRAKE ROTOR INFORMATION
EBC’s 2-piece replacement discs have been tested to withstand hundreds of hours the harshest track driving. All cast iron rings feature 48 curved vanes and are handed left and right, ensuring the vanes always rotate in the correct direction, giving maximum cooling efficiency. All outer friction rings are cast from a high-copper, high-carbon G3500 disc alloy giving them a high resistance to wear and cracking, even when used on track or for racing. 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, preventing unsightly corrosion and ensuring the outer ring continues to float freely, even after years of exposure to road elements. Each bobbin location also features an anti-rattle spring clip, meaning these discs are totally silent in operation.

BRAKE PAD INFORMATION

Engineered for high-performance track driving, RP-X™ delivers a consistent friction level of 0.55 across temperatures ranging from 0 to 750°C (Ambient – 1400°F), ensuring 100% braking efficiency from cold. This makes RP-X™ an ideal choice for sprint racing and hill climb events, where instant full braking power is crucial without the need for warm-up. Additionally, its strong initial bite and powerful brake response make it well-suited for various circuit applications.

EBC Brakes Racing RP-X™ delivers an exceptional 0.55 friction coefficient with 100% cold brake response from ambient up to 750°C (1400°F) – engineered perfectly for sprint racing, hill climbs, and circuit drivers who demand an immediate, powerful pedal bite without needing to warm up the pads.

Key Feature Benefits

• NUCAP® NRS® equipped for perfect pad bond strength and retention.
• Maintains a powerful and stable 0.55 friction rating all the way from freezing cold up to a scorching 750°C (1400°F).
• Premium stainless steel backing plates significantly lower heat transfer to the calipers and eliminate the need for blistering paint.
• Achieves maximum braking effect instantly from cold, making it the premier choice for sprints, hill climbs, and immediate track performance.
• Delivers an intensely aggressive initial bite and firm, commanding pedal response for drivers who favor sharp deceleration.
• Formulated to offer excellent track pad longevity throughout heavy endurance racing and circuit abuse.
• Designed strictly for competitive track and motorsport environments and is NOT R90 approved for public road use in European markets.
