Remember.. I said from STOCK ride height... not "my front end is prepared for lift off".. height.
. Bascially, pull everthing out of the trunk and inside the car. Jack the rear of the car up till the rear wheels come off the ground. Then slowly sit the car back down. The car will sit at it's "factory" height for a little bit. You can then measure and tell how far it will go down with the aftermarket suspension. Remember, your rear struts could also be as good as shot and causeing the sag... a couple 12's in the trunk won't really cause for that much (if any) drop in teh rear is the suspension is good. I had a system in my last CSVT and had no rear ass sag (on stock SVT suspension parts with over 100K on it.
