These "RACE" pads feature a more aggressive, performance minded compound then what comes standard in Baer's Big Brake Kits. While these pads can be run on the street, due to the more aggressive compound they will perform better in a performance application such as track day events and will produce more noise and dust. Each pad set includes 4 pads, stainless steel abutment and noise suppression hardware is available seperately. Replacement "Race" pads used in select Baer systems with the S4 Caliper
