Called the Nismo N Attack Package, the upgrade kit was revealed earlier in Japan so that regular buyers could convert their pedestrian Nissan GT-R Nismo into an even more track-focused supercar. For American GT-R drivers, Californian tuning house Steve Millen Sportsparts (known more commonly as Stillen) has now been chosen as the official installer for the package. The N Attack package takes all the lessons that Nismo learned in modifying the GT-R to set its famous Nürburgring lap time. Modifications primarily focused on improving high-speed downforce, reducing the car's weight, tuning the suspension to handle the 'Ring's "punishing road surface full of undulations," and adding safety gear like bucket seats to keep drivers in maximum control of the car.

For U.S. Nissan GT-R Nismo owners, Stillen will offer two upgrade packs. The $52,000 Nismo N Attack Package B Kit is intended for customers who will be street-driving their cars, and retains the four-seat capabilities of the standard GT-R Nismo. Opting for the full $98,000 Package A Kit (that's on top of the price of your GT-R donor car) is intended for track rats and deletes the rear seats.

Either package enhances a buyer's Nissan GT-R Nismo with a reflashed engine computer, retuned suspension springs and shock absorbers, new anti-roll bars, new front brake pads, a new carbon-fiber front fender with aerodynamic flic, a new aerodynamic front splitter, and an enormous carbon-fiber rear wing with two height and 12 angle adjustment options. The more involved A Package also adds new intercooler charge piping for the 3.8-liter twin-turbo V-6 engine, new front and rear limited-slip differentials, new Recaro full-carbon bucket seats, and a special carbon-fiber bulkhead in place of the back seats.
