Mgw will not carry over- the 2015 shifter is different.
long tubes will not fit, shorties will.
The track pack car has an option for svt 15" rotors with 6piston calipers.
Drive shafts will have to be customized to fit.
Todays wheels and tires will fit.
Minor adjustments needed for todays s/c, turbos will not fit!
Todays longtubes wont fit but it will just be a matter of time for the current header companies design them for the 2015. The factory headers will suffice til then!
You can forget about a live axle for this car unless you've got bux to burn. The cobra jet version of this car will have a live axle!
