Hey guys. I have a 1979 Pontiac GP with a 400, fiberglass hood and with the AC compressor and ac hoses removed. I have the original stock front springs and it actually rides pretty good (bilstein shocks). I'm looking to lower the car and will be installing the taller lower ball joint. It seems the moog 5958 coil spring should lower the front an additional .5 inch??? Others say 5660 would be better.
Why is it that even with guys putting in a 2" drop spring from UMI it only lowers the car by only a half inch? Is it that the original springs already sag substantially?
