SP Performance Cross Drilled and Slotted Brake Rotors are a unique design offering the best combination of cooling and out-gassing. Special features include the exclusive SP Sinusoid Curve chamfer that has no edge. This is accomplished by the use of an outer radius curve rather than a countersink. The radius curve virtually eliminates any edge on the surface of the hole. With no edge, there is less stress build up, thus reducing the chance of surface checking. This smooth surface also makes the rotor more pad friendly by reducing the wear of the pad caused by the friction scraping against a sharp edge. Each rotor is coated with SP's flat gray ZRC. It provides long-lasting protection against corrosion in the most hostile salt-water environments. After being applied, ZRC provides the highest level of galvanic protection. The film of ZRC is conductive. After the coating heats up during use, it bonds permanently to the metal surface. It will not allow the metal to corrode, even when the surface is scratched.
Note: Please check Title and Product Features to verify the vehicle application to make sure these rotors will fit your vehicle before ordering..../ 85-88 Oldsmobile Firenza - Front Cross Drilled and Slotted Rotors / oldsmobile f85
