On a straight line, SS and Mustang.

On a running circle, the 370Z probably.

On a track (where turns and "straight" lines are involved and thus both sides are taken into consideration), the SS and most likely the GT 5.0 beat the Nismo 370Z.

All im sayin is if ur gonna have a performance variant of a 370 makes sure its faster n handles better than the regular version...Smh wat they should do is kill the GTR and put the GTR's motor in the Nismo with better handling n all dat n sell it for 60k....

nissan seems a little lazy and unexciting when it comes to color schemes. Not much of nothing for the 2011 370z. It would be nice to see a little power bumb for the 370z to say 350 and nismo 370hp. Come on nissan look at what they did for stangs. I know they don't compete with one another but still...it would be nice to have an extra boost.
Or at least nissan could of given us a E85 option.

The mustang GT turned a faster lap time at VIR during the "Lightning lap" by a considerable amount than the Nismo Z tested a while back (before the brakes went and it was wrecked).

Telling ya, them stangs are quick!

Wished the Z had more competition with other car manufacturers. Maybe then they would of done more of an update on the Z. At least i think they would of. Hell the stang made a major update to compete with the SS.

Nismo Z would not be my Z of choice for the track. Give me a base + sport with intake, exhaust, suspension, and a tune. I bet it beats the Maro and is closer to Cayman S. Nismo weighs too much.
