A large part of racing is reducing excess weight.
With street cars, drivers' main concerns are safety and how the car handles in extreme conditions, while their principal concern with race cars is speed. Consequently, excess weight in a race car is undesirable. There are many changes you can make to a race car to drastically reduce its weight. However, it is important to remove the weight from the right areas of the car to ensure it does not become unbalanced or lose traction.
Instructions
1. Remove any unnecessary items from inside the car, including extra seats, carpeting, spare tires, tire jack, speakers and sound systems.
2. Remove all but one-fourth of a tank of fuel from the car. This will reduce quite a bit of weight from the car, making it move much faster. Siphon the fuel into a gasoline container.
3. Switch out heavy steel or iron engine pieces with aluminum parts. Replace the engine heads, intake manifold and exhaust manifold with aluminum pieces. Remove the air conditioning and heating system from the vehicle.
4. Replace glass windows and windshields with Plexiglass. Only replace the windows with Plexiglass if the car will not be used as a street car. In most states it is illegal to drive a car with Plexiglass windows. Removing the glass lightens a car by 50 pounds or more.
5. Replace steel panels with aluminum ones. To keep the weight distribution even, only replace key panels on the car: the front fenders, hood, roof and top of the trunk. If you switch out any other panels for aluminum, the car may not have enough traction.
6. Replace the wheel rims with aluminum ones. Replace stock tires with thin, narrow tires. The smaller the tire, the less heavy it is.
