Jaguar Alcon (Centric) brake rotors
These are the correct Jaguar rotors for Alcon equipped XKRs. (Mine is a 2008 Portfolio) These do have the proper unique "half moons" in the rotor rather than slots as pictured and the box is labeled "Centric." I have to assume that Centric was the original vendor for the rotors. Of course, the price is a fraction of what Jag wants for them.
