Thank you. You have rated this product.

Set of 4 brake pads, fits on 1994-2000 Miata and 2001-2005 Miata with Normal Suspension

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.

BRIAN'S APPLICATION NOTES: I first drove on these in Vintage racing a Triumph TR4-A....which is the same weight as a Miata. I really liked the bite of these pads and they worked great at tracks like PIR. Finally decided to try them on our 2007 supercharged track and autocross MX5 and again the bite is great and they have low temperature performance that other race pads can't seem to deliver sufficient for use as your ONE choice for BOTH autocross and track.

Wanted to say thanks. The exhaust system fit perfectly, no drone at steady throttle, but a nice sound winding thru the gears. And it does sound a lot like my old Alfa. The Racing Beat lowering springs are just right. Appreciate the tech advice and the service.

Hi There Good-Win Racing. I just wanted to thank you guys so much for the great customer service and quality parts. 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.
