Quick question on 93 SC spindle swap on my 89SC...

I am doing the 93 SC Spindle upgrade on my 89 SC, along with upgrading the calipers to the PBR Mustang calipers. I have the spindles, PBR calipers, both the SC and the PBR caliper brackets, all attaching hardware, lower control arms with new ball joints and bushings, etc. I have the rotors from the 93 SC, which have been turned and are ready for use, but, I have a question. These 93 SC stocker rotors, are they the same size as the puny rotors on my 89 SC (10.87" I think)? If so, if I had access to a 93-9x Mark 8, is their a dual piston caliper that will work with the larger Mark 8 rotors?

Thanks in advance,

Phil
 
The rotors are the same size. As I understand it, if you put the 13" rotors on it from the MK 8 you'll only need to change the bracket. The caliper is the same so you can use the dual piston PBR caliper with the MK 8 bracket for the 13" rotor.
 
I guess what I am asking is with the mark 8 brackets for the larger 11.57" rotors, can the PBR calipers be used on those instead of the stock 10.8" discs?
