Lowering a vette?
I've seen a couple of 75's and 77's that have been lowered a inch or so. They look good, BUT is there anything detrimental that could arise from this? How is it done on these vettes? I would assume the front has shorter coils. But the back? Would they take a leaf spring out of the original? Just curious.

For the back, you just have to buy longer bolts for the spring. You can also buy a composite rear spring that will come with the longer bolts so that you can adjust the ride height. A lot of the supporting vendors sell them. As for the front, some people just cut the springs, or you could buy some new springs from VBP that will lower your car about an inch and a half or so.

The backs are lowered by putting in longer bolts at the meounting end of the springs. Fronts are done by cutting the spring. I have heard that using a 550LB spring in the front will lower it by about 1" but don't know for sure on that.

cheap way is to cut your front springs, but keep in mind with this alter the spring rate thus alter the ride quality. Best way is to purchase #550 springs.

My car just barely tucks the top of front tire inside the fender and the rear has about 1" between the top of the tire and the fender lip. My front air dam is 3" off the ground. If you are careful, you can keep it pretty low
I actually lowered it just a touch more after this picture was taken. No problems, just have to watch out for large potholes and dips.

In addition to good looks, a properly lowered C3 also gains some handling advantages. FWIW, at Chevy Power book RR heights my Hooker sidemounts clear all but the tallest speed bumps with only minimal finessing. That said, the lower you go the more likely you may need stiffer springs to reduce/eliminate excessive bottoming, but IMCO if you're after improved cornering you'll probably need them anyway. In any event, it's a good idea not to lower so much that the odd manhole lid takes out your oil pan (
