PART NUMBER: 13-1022NC6
Drivers can still have a high friction brake pad without worry of the pad becoming too cold to be effective when the car is driven only moderately. For use when pad temperatures are under 600 F and peak temperatures are not over 1000 F. Widely used on Vintage GT and formula cars the R4-1 has gained great popularity as an excellent auto-cross, off-road and rally-cross pad material. Great modulation, consistent pedal feedback and the same rotor friendliness as our other Porterfield carbon kevlar compounds.
TRACK REPORT: SONOMA RACEWAY!
Back to back stints with two drivers in the fastest "A" and "B" groups at Sonoma Raceway for three day weekend and our NC Budget Big Brake setup with our Porterfield R4 track pads was flawless!
