Nascar
The three components of nascar are safety, the car it’s self, and the engine.
Without these things nascar would just be a death filled destruction derby.
The object of nascar is completing a set number of laps around a track
without crashing and finishing first.
The seats in a stock car have to be as modern as any other part of the car. The seats are molded to fit each driver and are molded tight sot that the driver do not move around when going around corners. After the seats have been molded they are fitted with cushions and a five point quick release safety harness made of heavy duty nylon webbing (Hester, 20-21)

The first step in building a NASCAR car is the computer generated design; NASCAR sets the standard that each team builds the car around. Next is the steel; the steel is used to form the basic skeleton of the race car. The third step in building the car is building the chassis and roll cage. (146) The engine housing is also formed in this process. Step four consists of installing the firewall which is composed of thick steel plates that separate the engine from the driver. A metal roof is
also added along with rear wheel wells. Metal fabrication is next five. This is where the rounded fenders, hood and trunk are made. These elements are made from sheet metal and bent precisely to create maximum aerodynamic performance. The final step of building the car is painting and installing decals. (Hester 22-23)
Drivers make the cars but the engine is what makes it fast These eight cylinder V8 engines can produce up to 800 horsepower this is about four times as much as your car in the parking lot. The NASCAR teams have strict rules to follow when they build engines, but its tuning that makes each engine different (Hester 24-25). The car engines work by turning the crankshaft. The crankshaft in a NASCAR car is able to withstand 8000...
