A Carbon Kevlar compound made to last a bit longer than the original R-4 compound. Porterfield’s R4-E pads have an average coefficient of .460 and perform best at temperatures averaging over 600ºF. The R4-E compound is designed to endure higher prolonged temperatures and still have pad life as long or longer than Porterfield R-4. This pad is great for club enduros events and applications where temperatures are at their maximum.
