The hub rings you are mentioning are a must... If you got those (all 4) then find a shop that does high speed balancing. I took mine to Butler Tire in Atlanta and they knocked off the old weights and did them right. Still have a slight vibration at around 90-95. But can accept that. You are right about the stock rims - they rode GREAT!!! But I wanted the look - so you make the sacrifice. Looking back - wish I would have had my stock rims chromed.
