Personally, I would.
For that one, I would go sport all the way (aero kit, and low-profile lip on the trunk would be the only things "looks-wise"). All else would be chasis/handling upgrades, and the highest quality forced induction tuning I could afford.
It would be an EXCLUSIVE track car. I just like that image of a stock-looking Z flying arould a track, in and out of the curves, looking oh so good
