A privateer Corvette C5-R leading a in the. Contents • • • • • • • • • • • Development [ ] The Corvette C5-R was part of a plan by General Motors and their brand to create a factory team to participate in grand touring races not only in North America, but also elsewhere in the world, most notably at the 24 Hours of Le Mans. GM had previously been against approving factory support for Corvette racing programs, although the 's had seen some support until they ended competition in 1989.

With the fifth generation Corvette however, GM chose to show the performance capabilities of the new car by using a more production-based racing car instead of the 'in-name-only' Corvette GTP. Their intentions were to take on and, who were already running in the category at the time.

General Motors chose the group of Michigan to build and develop the new racing cars, as well as to organize the racing team in preparation for a debut in 1999. Also assisted in the project, running a second team for a year. Since regulations in place at the time limited the team to using elements of production Corvettes, Pratt & Miller and GM used heavily modified road car mules to test out the engine and other equipment that the racing cars were to use.

Later, the actual race chassis were built, sharing only basic key structural elements with the road cars. A firewall was placed immediately behind the driver's seat in the cockpit, eliminating any rear visibility inside the car. A large diffuser and wing were added to the rear, while a splitter and vents on the hood were added to the front. Igra alias kartochki.

The front headlights were also replaced with protruding permanent units in place of the pop-up headlights on the road car. The C5-R initially used a 366 ci (6.0 liter) based on the road car's. This was replaced with a larger 427 ci (7.0 liter) engine several months later during the 1999 season, and became the standard engine for the C5-R for the rest of its career. Katech Engine Development constructed the C5-Rs engines, although they retained elements of the production LS1 units. Eleven C5-R chassis were built by Pratt & Miller between 1998 and 2004, with ten being used directly by Corvette Racing and one built purely for privateer use.

A twelfth car C5-R frame was built, but served merely as a test mule for the C6.R. Modifications [ ] As the C5-Rs competed over the years, numerous modifications were carried out in an attempt to improve the C5-R's capabilities against stronger competitors. Among the modifications were changes to the bodywork's aerodynamics in an attempt to increase downforce. The hood design was changed during the 1999 season to replace the small slat vents with a large open gap allowing air to exit more freely from the front grill. The third and fourth chassis built during 2000 were actually different from the initial two, due to being built three inches wider to improve cornering grip. Later modifications included some technology developed on the C6.R, including air conditioning systems for driver comfort and a rear view camera on the bumper and monitor in the cockpit to overcome the lack of a rear window. Racing history [ ] Corvette Racing [ ] With two cars completed, Corvette Racing entered the 1999 for the.

The Corvette C5-R of Canadian and Americans and managed to finish the endurance event in 18th overall, 34 laps behind the class-winning. After failures at the, Riley & Scott ran a few more rounds of the to finish off the year. A lone C5-R finished second in class behind a factory at, and again at. In 2000, Pratt & Miller took over as the sole Corvette team, once again starting the season at Daytona. The Corvette of Fellows and Kneifel, now joined by Brit, greatly improved on their previous result by finishing in second place overall, a minute behind a factory Viper and easily outperforming various.
