Project Mu P7R389 Racing 777 Carbon Metal Brake Pad Set - Circuit Use Only

The Project Mu Racing 777 (Triple Seven) brake pads are a high-performance, circuit-only compound engineered for serious motorsport applications. Developed in Japan drawing on real-world experience in N1, Super Taikyu, and the Asian Touring Car Championship, these pads deliver strong initial bite combined with outstanding endurance across the entire race distance.

Built around a Carbon Metal, asbestos-free compound, the Racing 777 offers approximately five times the wear resistance of conventional sport brake pads — making it equally capable in short sprint races and demanding semi-endurance events. The compound was refined using GT race data to achieve an ideal balance of heavy-duty wear resistance and consistent braking power throughout the operating temperature range.

Key Features:

• Compound: Carbon Metal / Asbestos Free
• Applicable Rotor Temperature: 300–800°C (572–1,472°F)
• Friction Coefficient (μ): 0.40–0.55
• Compatible with racing slick and semi-slick tires
• Compatible with larger aftermarket wheels and calipers including Brembo, AP Racing, and Alcon fitments
• Superior initial bite with consistent, fade-resistant braking power
• Approximately 5× the wear resistance of standard sport brake pads
