I have question, besides the Brembo braking system, and the 18" rims are there any other major differences. Mainly with the suspension is it different I mean a better suspension in the track model than in the base model.

 

Track also has:
HID headlights
viscous limited slip differential
VDC (with an off button)
front lip spoiler
rear deck spoiler
underbody diffusers

Base doesn't have any of those things from the factory.

Suspension, engine and transmission (6-speed manual) are all the same no matter what car you buy.

Cheers,

Aluminum pedals
Homelink Rearview
Power seats(I think)

And Cruise Control!

 

There are additional models bewtween Base & Track; you might want to check out the Nissan USA site to see what each model has.
