Description
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. It is our hope to change this perception by giving all our customers access to what is, our neck of the woods. Stock cars are dictated by rather restrictive rules. However, the technology and development programs are as sophisticated as just about any other form of motorsport. Extensive wind tunnel testing, CFD programs, 7-post rigs are standard in developing the most competitive cars.

Stock cars are large and relatively heavy steel-chassis racing cars, a combination of factors that somewhat prohibits maneuverability and handling. Given they tend to run almost exclusively on ovals, which generally feature large radius corners, this has minimal impact on performance. Despite all this, errors at these very high loads can be brutal on tires, and small mistakes can create big consequences. Stock cars have neutral handling, but do rely heavily on setup to be competitive. If you don’t like tinkering with setups, you likely won’t be competitive outside a fixed-setup environment.

Unlike circuit racing, the majority of downforce is not created aerodynamically, but via banking in the corners. It might surprise some to know these cars produce up to 2600lbs ~(1200kg) of aerodynamic downforce, which is very nearly on par with what GT3 cars would produce were they be able to reach similar top speeds, but stock cars do it without large wings or diffusers. The majority of downforce is created through ground effects, via the front splitter and side skirts, and of course some help from the rear spoiler.

The nature of ground effects means that you must aim to keep the splitter very close to the ground at all times. As the underside is not smooth, drag is also lowered by blocking airflow under the car. This approach requires running on bump-stops, or very stiff springs to prevent the car raising too much down the straights. Unique damping properties are also used in stock cars for the same purpose. The effect of this is to make the cars somewhat sensitive and edgy, but in finding the right setup and driving style, the car will just ‘work’.

We do not take anyone seriously with a name like yours.

And the tires are absolutely useless!
If the tires were actually this bad the company who makes them would be bankrupt.

Cars are way too responsive and twitchy

Otherwise, quite good

Did ya'll hear about the nascar driver that took a RIGHT TURN?

More ISI oval tracks need to be updated to DX11 too.

This has been a decent mod since released by ISI. I know they plan to keep their sites on it to try and win back some of the oval community. I can't wait for that day because I don't want to pay for iRacing and I can't find anything better than NR2K3. This mod is the shinning beacon in the night. There are already good skins out there to match the NASCAR guys. The AI don't quite have that pack racing magic in this and sort of spread out like road course racing does. It makes sense and that could be track related too. But that's one of the big things we need. That and I need freaking VR to really appreciate the driving in these things. Best of luck on development here. Many of us are watching in much anticipation.

Did you have the dx9 car before? If so you should already have it kinda and try to verify the game files.
