Description:
Transform the rear profile of your Cadillac CT4 with the EOS Carbon Fiber Rear Trunk with Integrated Spoiler (Part #TRUNK-1193-BKCF), designed for 2020+ Cadillac CT4 models and compatible with all submodels. This premium upgrade replaces the factory trunk lid with a lightweight, performance-inspired carbon fiber assembly that delivers both aggressive styling and functional aerodynamic enhancement.
Constructed from 2x2 twill carbon fiber, this trunk lid offers exceptional strength, reduced weight, and a high-gloss finish that elevates the CT4’s exterior presence. The integrated spoiler is molded directly into the trunk design, providing a seamless, factory-inspired appearance without the need for add-on components.
Engineered as a full replacement trunk, this EOS component reuses all factory hardware, including hinges, latch, and wiring, ensuring proper fitment and OEM-style operation once installed. Due to the size and precision required, professional installation is required to ensure correct alignment and finish.
