Bill,
I'd like to disagree about the plastic vs metal point you made. I have after
market street alloys with plastic hubcentric rings. They are an extremely
tight fit to the wheel (so tight that I thought they were the wrong size and
ended up inserting them with the aid of a rubber mallet ). The difference in
vibration before and after was extreme. From barely driveable to no apparent
vibration. So plastic rings are very worthwhile (IMHO)
Regards,
Alan Pozner
