Easy fellas on the "my Z is faster than the Nismo" based on ONE road test. That's presumptuous and foolish. One test proves nothing. There has been tests of the standard 370Z 0-60 from 4.7 all the way to 5.2sec. The Nismo weighs more or less the same as the base sport but has +18hp...unless it defies physics it will be the fastest of the 370Zs. Lets wait for more reviews to judge.
With that being said, I'm happy with my touring+sport and would rather spend the extra $ to customize to my liking
