A body kit is a set of modified body parts or accessories. It usually consists of front and rear bumpers, side skirts, spoilers, hood, and sometimes front and rear fenders and roof shovels. Buffers are shock-absorbing accessories that prevent further damage in the event of a collision. Side skirts are panels at the front and rear of the vehicle that sit low on the vehicle adjacent to the wheels.
You need to know exactly what the body kit is made of and what the parts are made of. It can be a fiberglass, carbon fiber, fiberglass composite, polyurethane, or durable material. Most aftermarket kit components are made of fiberglass, carbon fiber or polyurethane. Compared with other available materials, fiberglass is often touted as relatively cheap and because of its very light weight. However, fibreglass is also very fragile and can easily break on impact. Carbon fiber is also lightweight, but more durable and expensive than fiberglass. Polyurethane is both soft and durable, becoming a popular substitute for the above-mentioned materials.
When you upgrade your car, if you already have a toolbox, open everything in your bag and make sure it's the right toolbox. This involves making sure it will fit your particular car for a year, build and model. Be sure to check the installation instructions, even with the toolkit guide.
