USR slotted brake rotors by EBC are created for enthusiasts who want low noise from their brakes while aggressive driving or towing. Two sets of shallow slots cover all areas of the rotor surfaces so both pads and rotors wear evenly all the way across–preventing the grooves and ridges from building up that cause frictional noise. USR brake rotors also expel the heat, water, brake dust, and friction gas effectively to keep rotors cool and functional during street performance driving in any weather. USR slotted rotors by EBC feature a vented center for air to pass between both rotor sides, so metal expands evenly during use and the chance of warpage is minimized. They are designed for use with EBC Greenstuff, Yellowstuff, and Redstuff pads.
