Splitters are more than just an aggressive styling upgrade. Whether installed on the front, sides, or rear of your vehicle, they enhance its overall appearance by creating a lower, wider, and more performance-inspired look.
Aerodynamics & Performance
Originally inspired by motorsports, splitters and aerodynamic extensions are designed to help manage airflow around your vehicle. Depending on their design and placement, they can help reduce unwanted airflow beneath the car, improve aerodynamic efficiency, and contribute to stability at higher speeds.
Protection & Durability
Beyond aesthetics, splitters can also provide an additional layer of protection for your vehicle's lower bodywork. They may help shield vulnerable areas of your front bumper, side skirts, or rear bumper from minor scrapes and everyday road hazards.
Aggressive Styling
One of the biggest advantages of installing splitters is the visual transformation. By extending the lower lines of your vehicle, they create a more aggressive stance, enhance its body contours, and deliver a sleek, sporty finish.
Whether you're looking to enhance your vehicle's appearance or add motorsport-inspired details, splitters are a great way to take your build to the next level.
Winglets are vertical extensions that can be added to the ends of certain splitters, giving your vehicle a more aggressive, motorsport-inspired appearance.
When applicable, winglets are designed to complement the splitter and come finished in the same color or finish as your selected product for a seamless, cohesive look.
Please note: Winglets are only available on select products and configurations.
