my GTA's will clear the outside of the caliper, but a 3/16" spacer is needed for the outside of the caliper to not hit the back of the spokes. i tried a 15X8 wheel off a mid 80's Chevy 1/2 ton pickup that i had crudely drilled to the smaller bolt pattern for some reason or another, and it looked like it would clear but the studs wouldn't go thru the holes so i don't know for sure if it would clear- i'm hoping it would, because then i could get some 15X10 stock car wheels for it.. gonna also try a Monte SS aluminum wheel to see if it clears- i don't think it will, but i'll know tomorrow..
