5Lug Fox Rear disc fitment question (turbo coupe brakes)?
nnnk'... This is my question. I have the aero & ranger axels, but, instead of all of those other brake set ups I have read about. I have brakes and discs from an 80's Ford T-Bird Turbo Coupe. It is all a direct bolt on, except the discs. Because the Turbo Coupe had a 4 lug rear end, the rear discs are drilled to fit my 5x4.5 lugs. Noone ever mentions on the net about using the turbo coupe brakes. I heard they are the same as a few pre 93 mustangs rear disc brakes. My problem is that I am wanting to get an upgrade in discs, but I dont know what will fit with my calipers. I know my front discs will use the SVO discs. But I wonder if I can use the SVO 5 lug rears? Or what about 93 5 lug rear discs? Are those two discs I mentioned the same?
