Re: Why are people looking for the sawblades?
IMO is right. IMO the 1991 saw blades are the most beautiful corvette wheels
ever made. I hope everyone gets rid of them. Then I will have the last set. You all

Re: Suspension refresh
Did a Mini Cooper with poly a few years ago. It squeeked terribly in cold weather thereafter. Maybe
the poly is better now.
