Season 4 Car builds

There are two classes of production based cars to pick from. GS and ST. These cars run on the same tracks at the same time, but are not racing against each class, and have seperate points.

Due to a lot of testing we were able to build the cars in such a way as to mimic their real car counterparts performance. That is to say, they have minimal engine upgrades and maximum handling, with wide sport tires in most cases. Like the real cars in the real series, these are non-downforce cars.

Nearly every car represented in the real Continental Tire Sports Car Challenge, is represented here. Like the real series, there are more ST than GS cars to pick from. All the cars were tested to run within 0.10 of a second of each other giving them the level of equality you have grown to expect from an IFCA series. Evenso, each season we will make minor adjustments just as the real series does.

No microphones will be used. (teammates can use private chat)

The Grand Sport (GS) class features large-displacement 6-cylinder or 8-cylinder sports cars as well as small displacement 4-cylinder forced induction sports cars.

The Street Tuner (ST) class is for smaller 4-cylinder or 6-cylinder compact sedans, coupes, or roadsters.

The format is reminiscent of the original Trans-Am Series, combining conventional sports cars and touring cars, though the Trans-Am Series usually had a single driver per car, unlike the Koni series, which has two drivers per car. Some vehicles in the Continental Challenge have actually been painted to resemble the original Trans Am cars, such as the Boss 302 Mustangs of George Follmer and Parnelli Jones or the original Sunoco Camaro.

If its not listed you cannot have it installed to your car, if you are found to be running an illegal build you may be subject to a points deduction or a time penalty.
