Dana 60\'s with Alloy Rims I want to run 16" x 8" alloy rims (probably Eagle's or American Racing brand). Should I be concerned about having problems? I checked American Racing's website fitment guide and it listed a 17" x 8" rim as the recomended wheel for my application, a 1988 GMC K3500. Is this because of the Dana 60's brake caliper? Could a 16" x 8" alloy rim be used if I ground the caliper some like the guys running 15" rims do? Or are the alloys just so much thicker that this size just won't work at all?
