Autocross/Light Track
PART NUMBER: 61-1761F
DESCRIPTION
This high friction racing material has grown to be a very popular choice for drivers who need the highest possible friction with a low pad temperature. Developed and tested in the vintage racing community the R4-1 gives an average coefficient of friction of .56 with peak levels up to .600. Having tremendous stopping power, the R4-1 pad material can reach upwards of .5 friction level when pad temperature is a very low 200 F .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 carbon kevlar compounds.

Porterfield R4-1 - Wilwood 7812 shape
Bought these for my 124 spider, have driven highway,city roads, and back roads . They have a lot more bite than the Wilwood BP-20 that comes stock with the Wilwood caliper upgrade. stop after stop they get the job done. I love the way the way the brake pedal is easy to modulate compared and the bite is a lot stronger. If you are looking for a strong street/autocross pad this one is the one to get. I have tried other brake companies pads and have not liked them.
