TCR Production Car Championship - Cars and Builds

The American Club Racing (ACR) model was introduced in 1999. This model had suspension and engine enhancements focused on maximizing performance in road racing and autocross environments. Horsepower was, by the use of K&N air filters and smooth intake tubes, bumped to 460 hp (370 kW) in these models, while torque increased to 500 lb·ft (678 N·m). Weight was reduced by over 50 pounds (23 kg) by stripping the interior and removing other non-essential items such as the fog lamps (replacing them with brake ducts). The new stiffer, adjustable suspension removed another 14 pounds (6.4 kg) These models, which also have engine and handling modifications, has an "ACR" badge and 20-spoke BBS wheels.

A new ACR was added to the Viper line-up after the 2008 model year. Its upgrades were more drastic than the original, including street-legal racing tiresTemplate:Michelin Pilot Sport Cups which Michelin describes as "Ultra-High Performance Sport tires", two-piece brake rotors, adjustable suspension, and significant aerodynamic revision. No engine modifications were made, so power and torque remain at 600 hp (450 kW) and 560 lb·ft (760 N·m) as in the standard SRT-10. The ACR is street-legal, and is similar to the MOPAR Viper that Dodge displayed at various auto shows. Weight was also decreased by 40 lb (18 kg) by using the "Hardcore Package", without AC, radio, speakers, amplifier, trunk carpet, hood pad or tire-inflator. Its aerodynamic upgrades produce up to 1000 pounds (4.45 kN) of downforce at 150 mph (240 km/h), or roughly 10 times the downforce the standard Viper SRT-10 can produce at the same speed. The interior was upgraded only by the addition of a beacon-tripped lap timer (Hardcore Edition Only).

The Viper ACR was built alongside the standard SRT-10 at the Conner Avenue plant in Detroit. The aerodynamic components were produced by Plasan Carbon Composites and assembled to the vehicle by Prefix Corporation located in Rochester Hills, Michigan.

On September 14, 2011, on the Nürburgring Nordschleife, a 2010 Dodge Viper SRT10 ACR completed the sixth fastest production, street-legal car lap ever recorded with a 7:12.13 elapsed time. Chrysler's press release claimed a new production car lap record, although three faster laps had been recorded more than two years earlier, albeit by very specialized low production vehicles.

The Chevrolet Corvette is a sports car by the Chevrolet division of General Motors (GM) that has been produced in seven generations. The first model, a convertible, was designed by Harley Earl and introduced at the GM Motorama in 1953 as a concept show car. Myron Scott is credited for naming the car after the type of small, maneuverable warship called a corvette. Originally built in Flint, Michigan and St. Louis, Missouri, the Corvette is currently manufactured in Bowling Green, Kentucky and is the official sports car of the Commonwealth of Kentucky.

A Corvette has been used as the Indianapolis 500 pace car 12 times.

The historical name Grand Sport returned to the Corvette lineup in 2010 as an entirely new model series that replaced the Z51 option. The new model was basically an LS3 equipped Z06 with a steel frame instead of aluminum. It retained many of the features of the Z06 including a wide body with 18x9.5 and 19x12 inch wheels, dry sump oiling (manual transmission only), 6-piston 14" front brakes and 4-piston rear, improved suspension, and front carbon fiber fenders. Manual power train equipped G/S models receive a tweaked LS3 with a forged crank, are built in Z06 fashion by hand, and utilize a dry-sump oil system. A new launch control system was introduced for all models that allows for sub 4 second 0-60. EPA estimated 26 MPG highway, 1.0 G on skid pad.

Do we use the Viper rear wing or the Forza rear wing?

I think both are adjustable and are the same weight.  So I would assume either one unless Morphader wants everyone to use the Forza Wing.

No, mate...  Both wings are allowed because they are both adjustable  

Sweet.

But which one provides better downforce?

Doesn't matter which one you use mate, both provides the same downforce..

Front 162-287
Rear 340-641

Only difference is that the Viper wing can be painted and the the other not..
