Mancini XHD springs are 1 1/2" over stock height and SS springs are 2". Now be aware that the spring for the right side sits 1/2" higher than the left. This is for launching as that side of the car get more torque. I had to add a 1" raising block on the left to even everything out which now changes the length of the shock you need for that side or it bottoms out. Be careful what you buy and know all the specs as one thing affects another. The XHD are stiff like a SS spring. I now have to buy a full set of shocks for SS spring length just for that side, or you can have your car lower on one side. These numbers came from Mancini yesterday. Call them if you want to use theirs don't just order like I did.
