Friction: μ 0.40–0.43
Noise rating: SAE J2521 AA
Disc: Carbon-ceramic
SAE J2521 noise rating AA — on unmodified bare pads
Friction rises with temperature — exceeding 1.0 μ in fade tests
2,000+ vehicles on road · fewer than 5 noise cases
Ideal for: Carbon-ceramic street cars, including Ferrari and Lamborghini CCB systems
