RSL 2 is a low-metallic, resin-bonded material with steel and aramid fibers and strong heat resistance. It is designed to hold a steady friction level across a wide temperature window while remaining gentle on both pads and discs, making it a classic endurance choice. It is built for GT cars, touring cars and prototype endurance racing, but also regularly chosen for sprint events because of its modulation. Together with its mix of Medium-high friction coefficient, Long pad and disc life, Excellent friction stability versus temperature, and RSL 2E offers longer pad life for long endurance racing, this gives RSL 2 a confident, usable character. Overall, it stands out as a strong choice for drivers and teams looking for a pad that balances performance, control, and consistency in demanding motorsport conditions.
