DEDCRIPITION

Upgrade the upper rear profile of your 2020–Present Cadillac CT4 / CT4-V with this carbon fiber rear roof top window spoiler kit, engineered to follow the factory roof curvature and rear glass contour for OEM-level fitment.

Constructed from genuine 3K 2x2 twill weave carbon fiber, this spoiler delivers lightweight structural rigidity while maintaining consistent weave alignment across the full surface. The aerodynamic extension refines airflow separation at the top of the rear window, contributing to improved high-speed stability and a sharper rear silhouette.

The surface is finished in a high-gloss UV-resistant clear coat designed to protect against fading, yellowing, and oxidation while preserving deep carbon fiber clarity over time.

 

Installation is direct tape-on using automotive-grade adhesive backing. No drilling, cutting, or permanent body modification required. Professional installation is recommended to ensure proper surface preparation and long-term adhesion.
