ezobens,
To help eliminate wheelhop on YOUR Gto, do the following:
1. Check tire pressure (around 32 works for me)
(Many dealers overlooked lowering the tire pressure from 60psi.)
2. Verify that your dealer has performed the TSB regarding "thunk in trunk"
(Have someone inspect the floor pan and differential case for obvious
contact or movement.)
(This involves replacing the differential mounting bushings to prevent
contact of the differential case with the floor.)
3. Verify that the shipping spacers were removed from the front springs.
(They're orange plastic and they don't belong.)
Hope that helps.
