I also asked the question and was told no. The only difference in functional components is springs, shocks and tires. The wheels are different but the same size.

I plan on changing springs and shocks at a later date, and tire size when it comes tire time, maybe even the wheels. The ground effects, such as they are, would be a problem to change, and I think they make very little appearance difference.

With that said, had I had time to order a car, I may have talked myself into a Sport anyway.

Good luck,
