A bodykit or body kit is a collection of exterior modifications to a car, typically comprised of front and rear bumpers (fenders), side skirts, and spoilers. There are many companies that offer alternatives to the original appearance of the vehicle from the factory. Body kits components are designed to compliment each other and work together as a complete design. Despite this, the 'mix and match' approach is often seen on cars, where the front of one body kit will be matched with the rear of another.
Automotive body kits are usually constructed of either fiberglass or polyurethane. Polyurethane is popular with car enthusiasts[citation needed] because it is more resistant to damage and does not crack in cold weather. In some cases body kits may also be constructed of carbon fiber, which is a popular and lightweight material. However, carbon fiber kits are not as highly regarded among speed enthusiasts, because it is very costly for a minimal weight difference.
Factory fitted body kits are now becoming more common, perhaps in response to the growth of the aftermarket tuning industry in the late nineties and onwards. Many manufacturers now work in-house with their motorsport divisions to develop styling upgrades.
