Cadillac CT5 / CT5-V Carbon Fiber Rear Roof Window Spoiler 2020-Up

Enhance the upper rear styling of your 2020-Present Cadillac CT5 or CT5-V with this carbon fiber rear roof top window spoiler. Engineered specifically for the Cadillac CT5 platform, this premium exterior upgrade follows the factory roof curvature and rear windshield contour to deliver OEM-level fitment while adding a sharper, performance-inspired rear profile.

Constructed from genuine 3K 2x2 twill weave carbon fiber, the spoiler offers an excellent balance of lightweight performance and structural rigidity. The precision-molded single-piece design ensures consistent carbon fiber weave alignment and smooth contour transitions across the entire width of the rear window.

The aerodynamic roof extension refines airflow separation at the top of the rear glass, helping improve high-speed stability while visually enhancing the sporty character of the Cadillac CT5. A high-gloss UV-resistant clear coat protects the carbon fiber surface from fading, oxidation, and environmental wear while maintaining deep carbon weave clarity.
