G3 GT Race Car

G3 Motorsports G37 GT Race Car: 

G3 Motorsports is fielding one Infiniti G37 Coupes in the Grand American Rolex Sports Car Series GT division for 2008.
The Rolex Series class is home to production-based race cars that are similar in appearance to the latest high-performance sports cars and coupes that you see on the street everyday. Underneath their skin, however, GT race cars are all business and use some of the same leading technology found in the non production race cars. 

The rules for GT (Grand Touring) employ several methods of equalization including race car weight, tire size and engine rpm limits to provide an even playing field for a variety of international and American-made cars. With an eye toward the cost-containment and close competition, the current GT format will provide a stable battleground for the world’s top automobile manufacturers. The Rolex GT class is an awesome performance challenge that pits the Infiniti coupes against the likes of Porsche GT3s, Corvettes, Pontiac GTOs , Mazda RX-8s, Ferrari 360s, Maserati and BMW M3 coupes.

Engines in GT machines produce between 390 and 450 horsepower depending on the car, and minimum weights range from 2,500 lbs. to 2,800 lbs. The popular Porsche GT3s and BMW M3s – two championship winning models in GT over the years – weigh-in at 2,600 lbs. while the bigger Corvettes tip the scales at the maximum 2,800 lbs. Top speed for GT race cars is 170 mph.
