Shine street kit vs Sniper kit

I was looking at these two body kits for my 03 GS. I'm thinking of getting the the shine street kit but than i came across the sniper kit. It basically has the same front lip, rear lip, and sideskirts. The only difference I think I can tell is the rear wing. Plus it looks like the sniper will be less expensive.

I've emailed the company at shinestreet on a price quote of their kit but havnt received a reply back so could anyone tell me how much the SS kit is or the difference between the two?
