It all depends on high you want the car to sit in the back end. SS springs will raise the back about 2 inches over new stock height (2 inches is alot) but the car will sit with a slight canter with the right side being a little higher. A set of extra heavy duty springs will bring it up about 1 inch above new stock height but the car will sit level. I would not mess with air shocks or longer shackels.
