Besides a better variety of rims?? I was thinking about getting this conversion done but I have no problem with the 4-lug rims I have on there. As far as structure goes....is it better to have 5-lug?? I would rather spend my money elsewhere on the car.....conversion+new rims=more money for s/c or nitrous. What are your opinions? Plus 4 lug rims are really cheap.
