In addition to tuning cars, ings is also involved in the Japanese Super Taikyu racing series, and the N-SPEC series of bodykits are derived from the race cars used in the competition. The kit for the Impreza WRX STI consists of a custom front bumper matched to a new grille to give the car a more aggressive face while increasing downforce. Custom front canards accompany these modifications, while custom sideskirts and a new rear bumper can also be found on the ings-prepped Impreza WRX STI. A fog lamp attachment and cover are also available to match the OEM foglights on the hot-hatch.
The custom front bumper, sideskirts and rear bumper are all available in either fiberglass or a 'hybrid aero' fiberglass material. Hybrid aero fiberglass retains the positive characteristics of traditional fiberglass, including lightness and strength, as well as adopting traits such as flexibility and durability usually associated with materials such as plastic or urethane.
Meanwhile, the front canards and the custom front grille are available in either lightweight carbon-fiber or more affordable fiberglass. Each piece of the kit can be bought separately, but the custom front bumper, sideskirts and rear bumper can be bought as a three-piece aero package from ings. The price for the kit in fiberglass is ¥188,000 ($2,080), while the price in hybrid aero fiberglass is ¥218,000 ($2,410).
