EBC Porsche 997 Orangestuff Race Rear Brake Pads - Brembo Caliper (Inc. 911 Carrera 4, 911 GT3, 911 Carrera 4S & 911 Turbo S)Description Developed as a full race pad with a high friction level that increases with temperature. This material works best on light to middleweight high powered race cars where a higher fade resistance and wear life is desirable compared to Yellowstuff. Despite having an acceptable cold friction making this material street usable, the hot friction is deemed too high for ECE R90 approval and therefore this material is not road legal within Europe.
