gona need a front end wieght supe. we scaled my buddys nova and they picked a rate and it works and sits perfectly. when i asked them what to do if it sits too high they said do NOT cut the springs. call them and they will send what i need. they were very helpful. im gonna call them for a set for the gp when i get a chance. right now im running a moog v6 spring with a 1/4 coil cut off.
