Hey,
Some advice about buying kits off ebay, BE CAREFUL. I know a kid that just got a skyline body kit and not one of the four pieces fit correctly. Not only that, but some of the features on it gave him reason to believe that it wasn't even the authentic body kit. Im not sure if the aggressor is a full kit, but I know that the battle Z (blitz) kit is a complete 4 piece bodykit. I know wings west makes quality body kits but as far as style goes, they aren't very impressive. If reliability is the real question, I know of a website that my friend just got a nice body kit from and they have several kits for a 99 eclipse, including the battle Z kit. Heres the link, hope it helps.
