EBC Turbo Groove Front Brake Rotor Pair, XJ8 & XK8, 305mm. These fit first-generation XJ8 (1998-2003) non supercharged (all) and supercharged to VIN 853935. They also fit first-generation XK8 non supercharged to VIN 037347 and supercharged to VIN 031302. Equivalent to Jaguar JLM20150 & C2C-41249. EBC GD-Series Sport Slotted Rotors Made from virgin ingot and precision machined, GD-Series rotors are an upgrade over standard rotors and offer these advantages: Wide-aperture scraper slots help cool the pad surfaces and remove dust, dirt and debris. They also prevent the record-groove effect common to all non-slotted rotors to perfect and maintain good braking. Blind-drilled holes help to de-gas the brake pads (the build-up of gas between the pad and rotor or shoe and drum is more commonly known as brake fade.) Gold anodized finish for an attractive look.
