Road clearance
Where is yours sitting now?
This is what I have come across also.Another thing to consider is in some conversations and posts on the forum with techs that actually worked on the design process of the C5 they have often proclaimed that the jigs used to construct the front and rear sub-frames often produced minor discrepancies in production thus often cars did not ship at completely "square looking" ride heights; ride height was determined by proper corner weights.
This is one of the reasons why you shouldn't just go to town immediately turning down the bolts when you lower the car. Ideally you should turn the bolts even numbers of turns each side until you get the desired ride height.
If the car is between 27 1/2" to 29" on the tops of the fenders that's very roughly in the area of stock height. For sure if you're near 27" or below it's been lowered quite a bit.
