RSL 1 is a low metallic resin bonded material containing steel and aramid fibers with high heat resistance. It maintains a constant friction level over a wide range of temperatures. Its low wear rate and disc friendliness make this material appropriate for endurance races.
Used in GT cars, Touring cars and prototype endurance racing. Due to the high friction and good modulation, often used in sprint races as well.
