Super GT (stylized as SUPER GT) is a grand touring car racing series that began in 1993. Launched as the Zen Nihon GT Senshuken (全日本GT選手権), generally referred to as either the JGTC or the All Japan Grand Touring Car Championship, the series was renamed to Super GT in 2005. It is the top level of sports car racing in Japan[citation needed].
The series is sanctioned by the Japan Automobile Federation (JAF) and run by the GT Association (GTA). Autobacs has been the title sponsor of the series and its predecessor since 1998.

Purpose-designed for racing in the FIA GT Championship, at Le Mans and in other endurance races, the 550 Maranello has been substantially altered: The car has received a new bodywork, replacing all body components except the roof by carbonfibre and Kevlar parts. The re-designed, aerodynamic body looks very aggressive, sporting large air-intakes in the huge frontspoiler and a giant adjustable rearwing which generates a remarkable downforce. A completely closed bottom section and diffusors to the front and to the rear are additional elements of the 550 GTS’ optimized aerodynamics. Needless to say that the standard interior has been replaced by a very Spartan racing interior featuring a very stable roll-cage and an additional protective tube structure to the driver’s side. Weight has also been reduced by the use of perspex windows and the massive use of carbonfibre on the modified dashboard and center console. In total, the car’s weight was reduced by almost 600 kg to about 1.100 kg – which are almost perfectly balanced in a relation of 51:49. Unibal parts were used on the suspension, which is adjustable. The 550 GTS runs on huge OZ wheels in the dimension of 12’’ x 18’’ to the front and 13’’ x 18’’ to the rear, tires are Dunlop 280s to the front and 315s to the rear. Substantial changes to the engine include the enlargement to six liters (the 550 GTS now has a bore and stroke of 88 mm x 82 mm) and the fitting of a stainless steel sidepipe exhaust system. The 550 GTS produces about 600 hp and a maximum torque of 655 Nm, the maximum rev-rate is 7.000 min-1. Due to the FIA regulations, the engine had to be equipped with two large air-restrictors; without these restrictors, the power output of the 550 GTS would be even higher. The massive torque is handled by a sequential sixspeed gearbox attached to a Fichtel & Sachs MFX 200 racing clutch. The Brembo-made braking system features discbrakes with a diameter of 380 mm to the front and with a diameter of 350 mm to the rear. According to FIA regulations, the 550 GTS does not have an anti-lock system. The conversion of the car was performed by Baumgartner Sportwagen Technik (who did already prepare Franz Wieth’s Porsche GT2) and engine specialist Völkl of Tirschenreuth.

Utilizing a twin-turbocharged transverse V6 descended from the unit found in the road-going NSX, the car makes right around the 500 horsepower limit of the GT500 class. The NSX’s unique shape has adapted well to the aggressive aero package common in Super GT racing. In 2006, the efforts of the DOME team with the NSX would pay off, as the car won outright at Okayama. It’s worth noting that the substantially similar sister car, the #8 ARTA NSX, took second place overall in the class championship in 2005.

For use in the Super GT (formerly the JGTC), the NSX has been highly modified (as allowed by series technical regulations) with chassis development by Dome, engine development by Mugen, for Honda.
Externally the NSX shape has developed race by race, season to season to the demands of increasing aerodynamic downforce within the regulations. The most notable change is the position of the V6 engine, which is mounted longitudinally instead of transversely as per the roadcar. Similar to the setup used in modern Lamborghinis, the gearbox is located in the center tunnel under the cockpit and is connected to the rear differential by a driveshaft. Engines can either be turbocharged or naturally aspirated, depending on the class and on the rules.
Prior to rule changes beginning in the 2003 season, the Super GT/GT500 NSX was powered by a specially modified version of the C32B V6 engine. Using a stroker crankshaft from Toda Racing, the naturally aspirated engine displaced 3.5 liters and produced nearly 500 bhp. Beginning in 2003, Honda substituted a highly modified C30A, augmented by a turbocharger, which also produces up to 500 bhp.
The NSX continued to be used as the works Honda car in the GT500 class, even though it is no longer in production, until it was replaced in 2010 with the HSV-010. New 2014 regulations however will render the HSV-010 obsolete; Honda's 2014-spec GT500 car is to be based on the 2015 NSX, along with plans for a GTE version from 2015 onwards.

Cars were entered by Raybrig and ARTA in the 2005 Super GT season, Castrol Mugen Motorsports in 2000, Loctite in 2001 and Epson in the 2007 Super GT season.
