i am aware of all the dimensions and bolt patterns/offsets etc...that cause difficulty for getting rims to fit on a Z. i foiund a nice used pair with both 4 bolt patterns.....my question is as there are several companies that make adapters (with separate lug extensions) as well as just the spacer plates. what does physics tell us is wrong with all this - or is there? presumably you are adding unsprung weight but that will typ be more than overcome by the lighter wheels.....so is there some excessive wheel brg. wear that will occurr? and if wheels are properly balanced why is this? thanks in advance if anyone can help? and as datsun owners, can't we lobby that they make decent rims that still fit. (panasport/revolution aside)
