Today I received an email from RockAuto that the brake kits from Powerstop for the K5 have been discontinued and will never be in stock again. I've already had my rotors replaced once under warranty due to being warped. We all know this is a very common problem on the K5's. When it comes time to do my brakes I definitely will not use OEM rotors as a replacement. Does anyone know of a QUALITY set of rotors that are also IN STOCK and available for the K5?
