I just swapped a set of Porterfield R4-S pads in my Wilwood Superlight 6 Pistons. These pads are amazing. A little dirty and damn expensive, but 100% better than the Wilwood BP-10 "Smart Pads".

Has anyone else had issues with the Wilwood street pads?

 

i ran porterfields on the maxima for years. awesome stopping power. but damn will your wheels get dirty! Porterfield Brown!! hehe. hope youhave dark colored wheels.

 

great pads is true...but they ate up my expensive AP rotors in a few thousand miles
