About the RS-652 compound
RS-652 · The extreme hybrid
Seven years in the making. Endurance and sprint on both carbon-ceramic and steel rotors with zero fall-off, protected by a self-renewing 1–3 micron transfer film. Average friction 0.555 μ — measured beyond PAGID RSL1 (0.510) and Endless MA45B (0.438).
- 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
