EBC Racing RP-X Track And Race Rear Brake Pads For Nissan Skyline R34 25GT W/Sumitomo Calipers (RB25 Non Turbo)

The R34 Skyline 25GT with the naturally aspirated RB25 engine and Sumitomo 2-piston calipers is a balanced, enjoyable performer, but its factory rear brake pads are tuned for comfort and fade quickly when heat builds during spirited driving or track sessions. The EBC Racing RP-X Track and Race Rear Brake Pads are an ultra-aggressive compound developed specifically for dedicated track and race applications. With a strong, stable friction coefficient of 0.55 mu that performs consistently up to and beyond 850°C, these pads deliver powerful, fade-resistant stopping power and a very positive initial bite, making them ideal for the demands of serious track days, sprint racing, or aggressive road driving on the lighter 25GT.

RP-X provides high friction right from cold, requiring no warmup period for full braking effect. Compared to EBC’s RP-1, RP-X offers a 25% higher friction level with a much more aggressive bite, making it well-suited for the responsive character of the R34 25GT with its 2-piston Sumitomo calipers. While it produces higher brake dust and noise than milder compounds, this is the expected trade-off for maximum on-track performance and immediate response. The pads maintain strong modulation and deliver reliable, heat-resistant braking even under the most demanding conditions.

At Terra Firma Automotive, we supply these genuine EBC Racing RP-X Track and Race Rear Brake Pads as a premium upgrade for R34 25GT owners who prioritize outright track performance. They transform the rear braking system into a highly responsive, heat-resistant setup capable of handling repeated hard stops at high speeds while supporting serious track and competition use. For enthusiasts building a dedicated track weapon or high-performance street 25GT with Sumitomo calipers, these RP-X pads are one of the most aggressive and capable brake upgrades available.
