Last night I installed the larger rear springs. It looks like at dragster now with the back end much higher than the front...also seems like less road noise but could be my imagination. Tomorrow night the ball joints will be 'flipped' and torsion bars will be cranked. My question is this; "What is my reference point to adjust the VX to? I assume I want it to be level. Do I want to use a level on the frame in the middle of the VX? ...the window ledge?
