NASCAR is the name of a whole spectrum of sports competitions that has successfully existed since the 1950s. It all started with races of ordinary cars that are produced massively. This is what attracted riders and spectators, because there were cars that drove along the roads. It later they began to be finalized. About the 1960s, a serious arms race went, in which not only the racers themselves participated, but the auto producers themselves slowly began to connect.
In the 80s, everything fundamentally changed. New security requirements entered into force. At the same time, there were wide opportunities to attract sponsors. For example, cars could be applied to cars and get good support, which are still used by riders. Jeff Burton spent several races with a print of Caterpillar spare parts, which made it possible to bring his sheve to the racing ideal.
Speaking about security, it is worth noting that now not serial cars traveled along the track, but only their ghosts. These were car with a custom frame, which was lined with panels outside, remotely reminiscent of the outlines of the serial model. This has been done not only for the sake of safety, but also to equalize racers in terms of aerodynamics. By the way, the requirements include 3 dozen compulsory points, which should correspond to the body. The headlights here and those drawn.
As a windshield, a thin transparent layer of special material is used, covered with several layers of transparent film. In the case of contamination, the upper layer simply breaks down. Instead of the side glasses, a mesh made of elastic material is stretched, which will not allow the pilot to get hurt, in the event of an accident.
All, in fact, the same engines. V8 to 5.8 liters, calmly betraying more than 750 forces and dispersing a car to 350 km \ h. Developers are left an extremely small platform for creativity, as with the body.
Racers and developers, in fact, are driven into the narrow framework of the regulations. This is due to high speeds, the accident at which can become a fatal. In the European NASKAR there is less speed, they are limited by the configuration of the tracks, but the regulations from this are significantly not changed.
