Where those chrome 19's on there last weekend? I thought it looked pretty sharp. Please don't take offense to this, but I don't see your car really as a sports car. The same way I don't see my GTP coupe as a sports car either. (Some people say because it's a 2 door with a supercharger, then it's a sports car.) I think your car is more of a pimp ride with a little bit of oomph.
As far as launching, what is happening when you dump at 2500? Are you spinning or bogging? I dump around 3400 and get just a smidge of spin (or the clutch slips ) and I pull 1.9's.
