The EBC Brakes USR Slotted Rotor Sets USR933 are high-performance brake rotors designed for use in vehicles. These rotors feature a slotted design that helps to dissipate heat and reduce brake fade, providing improved braking performance. They are made from high-quality materials and are precision machined for a perfect fit. The slotted design also helps to remove debris and gases from the rotor surface, resulting in smoother and more consistent braking. These rotors are a direct replacement for factory rotors and are suitable for both street and track use. They are compatible with a wide range of vehicle makes and models.
