I doubt we'll get anything like race seats and harnesses given GM's history I have a hard time hoping for much as far as significant changes.
Some things that I think are possible and would like to or thing we might see:
- Updated tune with a little more boost to get over 500 HP, perhaps they can do this with intake/exhaust changes so as not to go through a fresh EPA certification
- CCB brakes from the 5BW
- Some weight reduction, maybe the mag wheels but I love the carbon roof idea
- Maybe they go the Porsche route and eliminate content to save weight but charge more
- Updated suspension tuning to be more track and less road focused. I'd be surprised to see DSSV shocks but maybe spherical bushings?
- BNG: Bold New Graphics
