EBC Ultimax Brake Discs - Ultra Quiet Sport Slotted Brake Rotors. The narrower multi-slot design and the progressive angle at which the slots are machined creates a quiet running sport rotor that still has the benefits of removing gas, dirt, water and debris and maintaining parallel pad wear.However please note: the trick is to opt for a matched set of brakes and not to just expect a slotted rotor to improve braking on its own. When used with higher friction EBC Redstuff, Greenstuff or Yellowstuff brake pads, these rotors will deliver a better braking performance.
