You could get WRX lowering springs and put 'em on it. We're running H&Rs on our racer now. Rear is still about stock height with all the weight lose but my guess is a stock SVX would be about an inch lower in the rear. Front is another story. You'd have to figure out some sort of way to raise the perch up about 2 inches or go with struts that have a higher bottom shaft. We're about 3 inches lower than stock with about 400lbs less weight up there. By the end of the week it will have WRX front struts on the rear too.
