Sitting lower may be a good thing; it was for me. Calvert will work with you on the ride height. It involves replacing the rear portion of the spring.
One thing often overlooked by those not running the Stock class but wishing to emulate a Stocker in suspension and leave characteristics is the fact many of these "hard leaving, wheelie poppin' vehicles" have a LOT of ballast in the rear. This is done to make the class minimum weight and / or to gain traction.
