Well then give the answer! It doesn't help any just to say, "not true!"

It can include more than the body kit, but when he said "kit" that is what I thought he was referring to!

There is an S-Tune package that includes more such as badges, suspension, wheels, etc. This is from motortrends site:

On the newly set up microsite, the S-tune package is clearly outlined, with mostly bolt-on accessories included. Comprising the setup is a full aerodynamic kit complete with front chin spoiler (nose extension piece), side skirts and rear under diffusers. On top of the hatch is a rear spoiler as well. Like with other mildly tuned S-tune enhancements coming from Nismo's Omori factory, a stiffer, lower suspension has been added to the mix, as have 19-in. forged aluminum LM25 model wheels.

A Weldina performance exhaust allows for the 3.7L V-6 to breathe a little easier and produce a throatier note. Additional chassis bracing and fade resistant brake pads should give the 370Z S-tune more ability in the twisties. Inside the cabin, Nismo-branded mats find their way into the foot wells, while logo embossed side sills ensure all who jump in know the S-tune is something other than a run of the mill model.
