A specific model of luxury vehicle, the Cadillac CTS, can be visually enhanced through the addition of aftermarket components. These kits typically include front and rear bumper modifications, side skirts, and sometimes a rear spoiler or decklid treatment. The effect is to alter the vehicle’s aesthetic profile, often resulting in a more aggressive or personalized appearance. An example would be a CTS fitted with a ground effects package and custom wheels.
Modifying a vehicle’s exterior provides a means of individual expression and can improve its perceived style. The incorporation of such kits can also, depending on the design and materials used, subtly improve aerodynamic performance. Historically, such modifications have been popular among automotive enthusiasts seeking to differentiate their vehicles from factory-produced models and showcase a degree of customization reflective of their personal taste.
