- Buick Ownership
I replaced the factory air shocks with Monroe 90007C suspension kit because the car rode rough in the back and sat too high.It rides better now but actually sits higher than before.Measured wheel gap of other cars at approx. 2 3/4".Before conversion my car measured approx. 3/12".After conversion approx. 4" gap.Will the car settle over time.Could the car have the wrong coil springs or something else that I am missing?GM lists about 6 different coil springs for this car.
