The Tokyo Auto Show gets underway this Friday, but already the exhibits of the major carmakers are hitting the web. Nissan released its set of show cars today, including a range of custom packages for the 370Z, GT-R and Cube. Nissan's GT-R super-coupe is shown off by NISMO in Club Sports form, which entails a custom chassis, carbon fiber bucket seat and titanium exhaust system among other tweaks. The car is tested to reduce the standard GT-R's lap times at Sendai Hi-land Raceway by over a second - all while preserving the factory warranty. Another GT-R, the Xanavi NISMO GT-R Super GT 2008 GT500 race car, and winner of the 2008 Driver's Championship, will also be on display. The 370Z, revealed in November at the Los Angeles Auto Show, gets a 'Fairlady Z Stylish Package' already previewed here.
