DP31515C Red Stuff brake pad set for 4 pot calipers. Since this material was introduced in late 2003, it has received many positive write ups from performance drivers of faster cars such as the Impreza. This is a truly impressive fast road pad for repeated heavy braking. It emits far less dust than semi-metallic pads and has been proven to stop a passenger car/saloon/sport compact/hot hatch 13 metres quicker than OEM pads from 100mph/160kph.
