they might clear the calipers, but with only 3.75" of backspacing on an 8" wide wheel, they might be hanging out in the breeze.
so far, i've had 3 different sets of wheels on my Nova with the 12" PBR setup- 15X7 1971 Z/28 rims, 16X8 IROC rims, and the current 16X8 GTA "honeycomb" rims. the 16's clear with no problems, but the calipers needed just a tad bit of grinding on the fins at the front and rear edges of the caliper to clear the 15" Z wheels. i haven't yet found another 15" rim to fit.
you don't plan sincerity.
you have to make it up on the spot.
wanna hear about 20 years ago when i was too smart to know any better?
