I need some info about the calipers . Im about to drop my stock 20s for some 17s and several guys have said its no prob but i just read a post about a guy who said his 17s didnt fit because the back calipers are larger than the front ones. so he had to go with 18s .anyone know the DEAL!!! and also whats the right offset for them . oh yea truck is 06 1500 qc 4x4
