Shortly after the unofficial release of the first photo of the NISMO-fettled 370Z (Fairlady-Z in Japan) we have yet another leak concerning the new 'Z' coupe and Nissan's in-house tuning division. This time someone managed to scan NISMO's official brochure providing us with further details on the S-Tune package for the 370Z. Even though everything looks Japanese to us, the black and white scans tell us that apart from the bodykit that comprises front and rear lip spoilers, side sills, a rear wing and larger alloy wheels, the S-Tune package will also include a full sport exhaust system and suspension and brake upgrades. Hit the jump to see the rest of the scans and if you happen to speak Japanese, don't hesitate to enlighten us with an English translation on the comment section.

We're just over a week away from the official unveiling of the Nissan 370Z, but a factory brochure of the NISMO S-Tune Z34 has leaked out from Japan, showing the two in-house tuned models buyers abroad can choose from when the new Z goes on sale later this year.

The first package is the NISMO S-Tune Aero Package that reduces lift and provides increased downforce through the use of a new nose, front lip spoiler, side skirts and rear spoiler. Also included in the package is a set of "fender protectors" – essentially mud flaps – and a set of NISMO-badged floor mats.

The NISMO S-Tune Performance Package is more our style, and includes a stainless steel exhaust, NISMO LMZ5 wheels – featuring five spokes and sized 19-inches – an S-Tune suspension, upgraded brakes and the obligatory floor mats. Pricing in Japan is outlined in the spec sheet, and you can check the gallery for a handful of images detailing what may (or may not) be offered in the U.S. later next year.
