Temperature range: 50–800°C
Friction: μ 0.49–0.57 (steel); rising with temperature on CCB
Discs: Steel + carbon-ceramic
Lock threshold: 95 bar (RS-635: 65 bar)
+46.1% lock threshold — 95 bar vs 65 bar
On CCB, friction rises with temperature — 0.689 μ at 800°C
Disc wear 0.001 mm — 1/9 of RSL1, 1/18 of MA45B
Ideal for: TCR, GT and touring-car racing on steel or carbon-ceramic discs
