We are starting to build a 2005 grt underrail crate with 604.the car had been updated with the clevis style uppers and one pc lowers.question is does anyone know of a good startin point on springs
,shocks,bite and percentages..i know u could go by the main site of grt but i believe that would be based on a higher horsepower motor and all aluminum engine..anyone have any goodstarting setup for this car?thanx
