The front bumper cover has a lip to it, and the rear wing is a fixed wing. No pop up spoiler. Wheels are different. SRT has more spokes. Remap is actually a new tune done to the ECU after you have done all your modifications. Like if you add a Needswings dual cold air intake, you would have to tune for that. Personally, I would read thru some of the threads on here. The 3 easiest mods, and the best bang for the buck, is a cold air intake of your choice, a new supercharger pulley 65mm, and a tune by someone like Eurocharged. You will see significant improvement in acceleration.
