R4-1 Brake Pad

The R4-1 is designed for vehicles that have trouble keeping heat in their pads, such as vintage and classic vehicles.

Developed and tested in the vintage racing community, the R4-1 gives an average friction level of .56 with peak levels up to .600. Having tremendous stopping power, the R4-1 pad material can reach upward of .5 friction level when pad temperature is a very low 200F. Drivers can still have a high friction brake pad without the worry of the pad becoming too cold to be effective. For use when pad temperatures are under 600F and peak temperatures are not over 1000F. The R4-1 is an excellent auto-cross, off-road and rally-cross pad material.
