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.

RST 1:

PAGID RST1 High average friction, aggressive in stop behavior with instant pedal response and release, consistently firm pedal at all temperatures, fade resistant at highest disc temperatures.  High friction compound with very good initial bite and a progressive torque curve. Very fade resistant.  Suitable for applications with high down-force and / or very high grip. 

RST 3:

RST 3 is a medium-high friction metal-ceramic compound containing steel fibers and is therefore the perfect complement of the RST product family. It captivates by its low heat conductivity. Popular applications of the RST 3 compound include rally tarmac and gravel, GT cars, Touring cars and prototype circuit racing, formula cars and club racing. Wide range of applications due to it‘s combination of bite, friction and controllability.

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.
