I am planning on putting new ball joints, tie rod ends, and bushings in my car and have been thinking about replacing the springs at the same time. The PO installed 2 inch blocks in the rear and I'm not sure if he cut the front springs or torched them but the ride is awful and the front tires rub the inner fenders at full lock. I would like it to sit about an inch higher than it is but it wouldn't hurt my feelings to sit at the factory height either. I keep reading about people using Aerostar coil springs. Aside from the cost and the fact that they look to be a progressive spring, are there other reasons? According to MOOGs website they are 605 lb, 11.65 inches, 4.07 inches ID, 3/4 inch bar stock. I don't know what the original spring rate and dimensions are. I'm not looking to go drag racing, I just like to use it as a mostly daily driver.
