I bought an 03 in may of this year with that z51 suspetion the car has 145 miles I feel every crack in the road like i just ran over a dog does anybody really likethis z51 suspention or did i make a big mistake. will it ever ease up? or should i disconnect the battery and save it as a trade on a c6?

Z51 is the performance handling option. ( Stiff ) Disconnecting the battery is not going to do anything. If you had the Mag Ride ( F55 ) option, I would say that you still had the shock stuffers in place. People are still finding these things in their cars that the dealers forgot to remove. One car I know of had over 20, 000 miles on it. But the stuffers are only on Mag netic Ride cars. If you misquoted your option look for a little yellow ribbon hanging out of the shock boots. If there take it to your dealer immediatly and raise Cane
