I'm not sure what a stock measurement would be. Maybe VX KATT, Vx Sport or someone could chime in here and answer that. All I know is that I have a 3" suspension lift with the 22" measurement from the centerline of the axle to the bottom of the fender clad. (correct me if I'm wrong anyone)
It seems to me that you are at stock height or slightly less. Did you jack-up you're car so the wheels were off the ground to relieve the load on the torsion bars when you torqued them??
