Hey guys and gals......I have a 87 that rides like a lumber wagon. Not sure about the roads in the good old U.S.A. but up here in Canada the roads are horrible. Should have bought a 4 wheel drive instead of a corvette. Is there anything I can do to get a better ride out of the car......new spring.......better shocks......The car has the Z51 package which does not help I suppose...how about coil overs? I read somewhere that could be an option. There is a lot of knowledge on this forum hope someone can advise me...It is my first corvette. I have had hot rods of all types but never something that rode like my C4.
hope you can help
