I had a 2005 vert and the springs are definitely different. The weight distribution of the roof requires a different shock or the rear will sit more than the front if you are lowering. Shocks and struts were the same.
The rear sway bar is way different. It has different bends to it so it can clear the body brace bars the Vert's have. Also the springs are different to carry the extra weight between the two models, coupe or vert.
