This update consists of brand new tire compounds for every track the Gen 6 CUP cars run on that are available in rFactor 2. A lot of development was spent making sure they reacted correctly, giving the car a much improved feel and a better sense of realism. The main component of this update is the tire model. We've been hard at work for nearly 16 months redesigning almost every aspect of these cars. Extensive wind tunnel testing, CFD programs, 7-post rigs are standard in developing the most competitive cars. However, the technology and development programs are as sophisticated as just about any other form of motorsport. Stock cars are dictated by rather restrictive rules. It is our hope to change this perception by giving all our customers access to what is, our neck of the woods. Stock cars, undoubtedly the most popular form of motor racing in the United States, is often seen as primitive by Europeans and much of the rest of the world.
