Porterfield Carbon Kevlar R4-1 Racing Brake Pad:
  AP 227 R4-1 

Porterfield R4-1 Carbon Kevlar Racing Brake Pads were developed and tested in the Vintage Racing community. Because of the high coefficient of friction (?) at low temperatures, these are fast becoming the Autocross brake pad of choice. A peak Mu of .600 the R4-1 pad can reach close to a Mu of .500 at temperatures as low as 200?F. The R4-1 brake pads are widely used on Vintage GT and Formula car where pad temps are under 600F and peak temps are below 1,000F. This is also a good Rally-Cross brake pad.

Typical AP 227 R4-1 applications are Audi Coupe, 4000 and VW Golf, Jetta, Passat and Scirocco front brakes.

Made in the USA
