The problem with the diablos is that they look quite small, as the spokes dont reach the outside of the rim, so really theyd look an inch smaller than they are. You could get some kahn rims, either the rsr or rss in 16inch and theyd look like 17s. I dont know much about the valvers other than they dont seem to have a lot of torque, which could prove 2 b a problem with 17s.
