Well I'll tell ya what the Baer Calipers and Rotors I have have the .875 wide rotors, which were used on both the Corvette and Cobra and are the directly from Baer. Reason I'm changing over to the FORD COBRA PBR Calipers and Rotors is because of being able to go to the local auto parts for parts. Also have been breaking the Aluminium Hubs from Baer and at $225.00 each. Now everything in the front end including the spindles, hubs and rotors will now be all Ford Cobra which will also be the 1.1 inch rotors.
