An aftermarket modification package designed to alter the external appearance of a specific model year vehicle. These kits generally comprise components such as front and rear bumpers, side skirts, and potentially a rear spoiler, all intended to provide a more aggressive or personalized aesthetic. An example would include a collection of molded plastic or fiberglass pieces specifically shaped to fit the contours of a seventh-generation compact car, altering its factory appearance.
The appeal of these modification packages stems from several factors. They offer vehicle owners a means of distinguishing their vehicle from others of the same make and model, reflecting individual style preferences. Furthermore, certain designs can subtly improve aerodynamic properties, although this is typically a secondary benefit for street applications. Historically, the availability of these kits expanded significantly with the rise of tuner culture and motorsports-inspired styling trends.
