The time has come to replace the warn out, sagging springs on the Buford. I'm leaning towards Detroit Eaton Spring as they will make a set of dropped coils to my specs. Now the question is, what ammount of drop should I be seeking? I'm not looking to totally put the car in the weeds, but I'd like to fill the wheelwells and give the car a bit more of an attitude. What ammount of coil drop can I get away with before I interfere with pinion angle and front end geometry?
