Hawk OES (Original Equipment Service) premium ceramic pads are engineered to be ultra-quiet, low dusting, long lasting, easy on rotors. The pads' OE-grade shim technology boasts a noise-dampening friction formulation and they are 100% chamfered and slotted for optimal brake performance and smooth engagement. Hawk OES pads produce elevated stopping power over OEM pads, which combined with their smooth engagement and exceptional durability generates less dust and keeps wheels cleaner. The end result is less wear and tear for the driver and a longer-lasting ceramic brake pad. These pads are perfect for the street and are not recommended for track use.
