Nismo wheels are .5" wider front and rear, car has SRM and Sport brakes.

New springs/shocks/struts lower the car and are a bit stiffer.

One damper on the front of the frame-rails by the radiator to stiffen the front end, along with the strut tower brace which has extra bracing. Then there's a rear damper attached to the rear sub-frame, which is really the only part that isn't a direct bolt-on, as the non-Nismo cars don't have the attachment points. Everything else is transferable.
