Cadillac ATS-V Carbon Fiber Extended Front Splitter Side Wheel Arch 2016-2019

Enhance the front-end aerodynamics and visual presence of your 2016-2019 Cadillac ATS-V with this carbon fiber extended front splitter side wheel arch set. Designed specifically for vehicles equipped with the EOS Carbon Package front lip splitter, this upgrade extends the aggressive styling of the factory aero system while maintaining precise OEM-level fitment.

This extension kit is engineered to seamlessly integrate with the existing front splitter, continuing the aerodynamic flow into the wheel arch area for a wider, more performance-oriented appearance. The sculpted design enhances the lower bumper profile while improving airflow management around the front wheels.

Constructed from dry pre-preg carbon fiber, each piece is autoclave-cured to ensure maximum strength, lightweight performance, and consistent weave quality. Finished in a high-gloss UV-resistant clear coat, this upgrade delivers a premium OEM+ look suitable for both street and performance builds.
