Cadillac CT4-V Blackwing Carbon Fiber Front Splitter Side Wheel Arch 2020-Up

Enhance the front-end styling and factory performance appearance of your 2020-Up Cadillac CT4-V Blackwing with this carbon fiber front splitter side wheel arch extension set. Designed specifically for Blackwing models, this left and right pair refines the outer edges of the front bumper and wheel openings to create a wider, more aggressive front profile while maintaining OEM-inspired styling.

Each wheel arch extension is constructed from real dry prepreg 3K twill weave carbon fiber and autoclave-cured for lightweight strength, consistent weave alignment, and improved dimensional stability. Compared with lower-grade wet-lay alternatives, this advanced dry carbon construction provides a stronger and more rigid component suited for performance-oriented street and track builds.

Styled after GM factory carbon aero components, these extensions follow the exact contour of the CT4-V Blackwing front fascia for seamless visual integration. A high-gloss UV-protected clear coat preserves the depth and clarity of the carbon weave while protecting against fading, discoloration, and environmental exposure over time.
