What I want to know is what the difference a sport version has vs. the standard? I didn't mean just the steering wheel. Is there a difference in the springs package, wheel, engine etc....?

 

The sports-package comes with bigger wheels(on my model they went from 15" to 16" wheels), a sports suspension(stiffer ride but better handling), and the sports steering wheel(which is a little fatter).

That's about all I know, might be more...could be less for your model...

 

if i buy just the wheel, will my airbag transfer over?

 

nope
