Cadillac CT4 Carbon Fiber Rear Trunk Decklid with Integrated Blackwing V2 Spoiler 2020-2026

Enhance the rear styling and aerodynamic performance of your 2020–2026 Cadillac CT4 with this Carbon Fiber Rear Trunk Decklid featuring an Integrated Blackwing V2 Style Spoiler. Designed as a full trunk lid replacement, this upgrade delivers a clean factory-plus appearance inspired by Cadillac’s high-performance CT4-V Blackwing.

The integrated spoiler is molded directly into the trunk decklid, creating a seamless aerodynamic profile without the need for bolt-on spoiler components. This design maintains the original body lines of the CT4 while adding a more aggressive and performance-focused rear-end appearance.

Constructed from high-quality carbon fiber, the trunk lid offers a lightweight yet rigid structure compared to the factory metal panel. The exposed carbon fiber weave is finished with a UV-resistant gloss clear coat that protects the surface from fading and environmental exposure while preserving its premium appearance.
