I have the "new" SS springs, from Mancini in Aug '08. I did have to add an extra leaf to the right side. The car felt like it was going to roll over on it's side when I launched. I had an old set of SS springs and used the 2 leaf from that set and added it between the main and 2nd leaf on the right side only. Problem solved. 11.5 tires, SS springs, non adjustable shocks (MP long, 50/50) NO pinion snubber and a Turbo Action "J" convertor, footbraking. Sitting still, the car sits up higher on RR, partly because of the extra leaf and partly because of the way I have the torsion bars set. But it leaves "square".
