Check with the template b/c when I went to mount my Bullitt's, I tried a bunch of different wheels and it seemed as though the back part of the rim is always rolled or cast different.
This can AND will cause a problem with the caliper hitting either the rim in the middle where it "humps" or at the spokes or if not spoked, the rear mount surface.. OR BOTH!!!
Plus, depending on rim diameter and back spacing, you may definately want to check the upper balljoint lip to rim lip as well as the outer tie rod end!!
Been there, done that b/c I made my own template!!
But this may not concern you b/c my combination is 17" x 8" w/ true 5.47" b/s with the rotor mounted AND 1988 Vette, 13" front rotors and big single piston calipers along with homemade brackets! My cheap "pdqCBB" setup.....
