Side and rear need to have a little job to match up a bit. Front looks not refined enough. Wing? Probably need to learn from 80's Porshe wing (or maybe VW Bettle). 350Z is not suitable for those GT design or so. It born to be in classy type, just like its name, Fairlady.
Interesting year indeed with the release of the Goodyear F1 SS series and the new Hankook S1 Evo 3. Falken FK510 still seems to be the best value for money though.
