Talk about quick off the mark. Nissan’s all-new Z34 370Z may have only been on sale in Japan for just two days, but a range of aftermarket options has already appeared on the scene. Nissan’s in-house tuning company Nismo has rolled out its S-Tune package for the 370Z, bringing even wilder styling, sharper handling and a smidgen more power to the curvy coupe.

On the outside there’s a lower lip spoiler and nose extension piece for the front bumper, wider and more deeply sculpted side skirts, a huge wing on the hatch and a pair of rear ‘under protectors’ round back. The S-Tune also gets a set of 19-inch Nismo rims, with a staggered setup making the rear hoops wider than the fronts and helping them fill out those massive fenders.

Performance mods are relatively light, with a Weldina stainless-steel exhaust being the only power-adder. Handling is perhaps where the S-Tune really shows its worth though. With Nismo-tuned dampers, stiffer springs, grippier S-Tune brake pads and no less than three chassis-reinforcing braces installed, the S-Tune should be just the thing for attacking a winding mountain road.

Prices for all these parts are still a mystery, but for us they’d be largely irrelevant: the Nismo 370Z S-Tune is a Japan-only proposition for now and there are no plans for export. Bummer.
