EBC Sport Rotors feature wide aperture slots that draw cool air into the braking contact area and reduce temperatures preventing brake fade. Dimple drilling avoids stress cracks and the anodized EBC finish provides a great look while preventing corrosion. EBC Sport Rotors now feature reduced 3 slots venting which provides slightly less air noise under heavy braking while still maintaining the benefits of cooler running with the full width slot design. Some wind noise is observed and if drivers feel they would find this offensive they are advised to select the quieter USR Ultimax Slotted Rotors or the EBC OE Replacement Rotors. Another great feature of slotted rotors is the way the pads remain flat and have uniform pad wear, while also avoiding the record grooves or galling common with non-slotted rotors. This improves pad contact and braking throughout the life of the rotor and pad set.
