R4-S High Performance Street and Autocross – For high performance and heavy-duty street conditions.  Perfect for prolonged everyday street use while also being capable of tolerating the most severe street use without any fade.   Rotor friendly of course.  The R4-S friction level will give you an impressive increase in stopping ability with very minimum pedal effort.  R4-S compound has the absolute lowest noise and dust levels, far below OEM equipment or any other high performance brake material.  Good for autocrossing, some drivers schools, solo events, and rally’s.  The R4-S compound is available for virtually any vehicle sold in the US.  We also offer the R4-S in pad sizes for competition type calipers that are used under street driven conditions.
