RSL 1: 

PAGID RSL1 racing compounds are complex formulations with very high content of ceramic materials. The difference to competitors metallic compounds is the superior thermal insulation and the higher heat resistance of ceramic compared to iron. Ceramic has a very low heat conductivity, so less brake disc temperature goes through the pad to the caliper. Pagid have measured up to 140 degrees farenheit difference in temperature compared to competitor pads.

Pagid RSL brake pads were developed to comply with the latest requirements in endurance racing and to accord to ecological standards in the automotive industry. They feature excellent pad wear under endurance conditions, excellent disc life, are less aggressive than RST pads giving best possible brake balance, modulation and consistency of friction under endurance conditions.
