- 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
