Eibach's Pro-Kit springs come in an A-body variety. They say they lower the front @ 1.5" and the rear @ 1". But since they are basically made for Chevelle's (probably with a small-block), I'm not sure how much they will actually lower a heavier big-block car.
My 1970 GTO has a great stance with them on, but it's not much different than I had with badly sagging stock springs.
Anyway, they are a great progressive-rate spring. I found a set of 4 for @ $260.
