OK here is what I know, as for the SN95, if you stay with 94-95 spindles the offset stays the same, anything newer and the wheels will be set out further. Baer makes a 12" kit for the fox spindles. If you go with the sn95 spindles, use the 99+ calipers, you have to clearance them slightly on the spindle for them to fit, they are dual piston PBR's on 11" rotors. If you go 13" rotors you will need 17" or larger wheels. Go to discbrakesrus.com and you can read all this information. Foxbody Saleens upgrade was merely the 73MM MK VII caliper and 5 lug rotor nothing more.
