I picked up my C6Z a few months ago and the car was slammed a little too extreme for my driving style so today I decided to raise it an 1". It came with Pfadt so I downloaded the pdf last night and it seemed pretty straight forward.
Well today I discovered that the locking nut was never tightened or vibrated lose on the right rear and left front. Anyone else have any issues with the set screw backing out and allowing the collars to unwind?
Next will be the alignment.
