I have mounted on my car 17" x 8" with 5.72" b/s, Mustang Bullitt rims!
Front brakes are 1988, 'Vette, 13" front rotors, my homemade, big single piston caliper bracket and single piston caliper all on two piece disc hubs less disc's and a 7/16" spacer and finally Ford bolt pattern, 1/2" studs!!
Rear is 1989 Camaro, 11.75" rear calipers and again my homemade caliper bracket and 1980 Cad. Seville rear caliper and 7/16" spacer and again, 1/2" studs.
Tires are 225 and 255/45-17's and I wished I woulda went 225 and 275/50-17's IF I could find them??
Brian made the front backets and Doug10 made the rear brackets, (if anybody is interested in them), after I carved out the first set of fronts out of 5/16" thick steel plate by hand the hard way!! Let me know at home.
Bttt, I took the time and made a caliper mount/inner rim fit cardboard template and went around to several of the local stores that sold wheels and took them off the wall displays and used my template to see if any "as sold" rims would fit my homemade brake combination so it may pay you to do the same thing if you haven't already done it.
I think the Baer site has a down-load template to start you out with if you want to search..
PS., later, much later I found out that there is a company that is repopping the Bullitt rims and in the Chevy bolt pattern!!!! Go figure.....
