Racing Parts
Racing parts are the individual bits that make up a race car. They are the tires, the fiberglass body. The engine, the drive shaft, the pedals, the steering wheel; these parts make up a car. If you can point to it, and it’s got a structural name, it fits into this category.
Some racing parts are meant to be replaced (sometimes several times) during the course of a race. Wheels are a prime example of this. Race wheels come outfitted with lug nuts, so that a change can be made without fumbling for new nuts. The wheels themselves are swapped out in their entirety each time a change is made. A total pit stop takes less than a minute, and that includes changing four wheels, refilling the gas tank, and any other service the car needs.
This emphasis on speed is part of what separates racing parts from the mundane car parts you put on a factory car. When you take your car to get the wheels rotated, you’re lucky if you have your car back in an hour. If a race car had to put up with that, it would never win. The other major difference is in adherence to rules. Your street car has to comply with federal regulations to pass inspection. A race car on the other hand has to comply with the league rules for engine makeup, parts quality, and material composition.
