High friction racing compound with high content of ceramic materials, fade resistance up to 700 deg. C (1,300 deg. F). It combines a 20% higher friction value than the rs14 with a slightly increased pad wear. Although the rs15 has a good controllability and release characteristic it needs finesse to avoid over braking the car, especially with lightweight cars or cars with boosted brakes. Applications: touring cars, rally cars (tarmac), GT cars, wsc, high down-force single-seaters, nascar.
