After checking rotor prices and availability from our closest supplier, we decided to have the rotors manufactured ourselves. We had 2 sets made thinking that someone might be interested in the other set. So here they are. This is a complete set of 4 brake rotors (outer rings only). You WILL need to use your factory hats. We will only sell these as a set. We are asking a mere $2495.00 for the set. This is cheaper than one front rotor from the dealer. These rotors fits 1999 to 2008 Diablo. Please contact us if you have any questions. You can call us at 205-251-1472. Ask for Jeff. Or e-mail us at support@hesco.us.
