Thank you. You have rated this product.

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.

Please note: These pads are made to order. Allow at least five business days.

REVIEWS

I absolutely love my Roadster Sport headers, mid pipe and Q muffler. I have owned a lot of cars over the years and the quality of your product is truly exceptional. The ability to tune the Super Q is very much appreciated.

My 91 MX-5 is running awesome thanks to the parts I put on it from your website, racing beat sway bars, racing beat endlinks, racing beat muffler, magnaflow catalytic con, shifter parts, and a few more. Thank you so much for making your website so knowledgeable and easy to get all these awesome MX-5 parts. My MX-5 handles, drives, and sounds awesome with all the new parts, Thanks a Million!! I look forward to ordering a new exedy performance clutch and light weight flywheel from Good-Win Racing in a couple months.
