after swapping out a couple different sets front & back, I finally decided on a set of "firm ride" moog springs through amesperf for the rear.......& put a set of stock replacement moog for 70 gto with a/c for front. I was told since I do not have a/c ,this will give me about 1/2 inch over stock height. for tires I am running 15 x 7"s with 235-60 series. I am very pleased with the stance. good luck with your choice...BTW @ rocker front 11 inches....@ rocker rear 11 - 1/4 inches
