Product Overview
Enhance the front-end precision and factory performance styling of your 2020–Present Cadillac CT4-V Blackwing with this GM Factory Style Carbon Fiber Front Bumper Wheel Arch Extension Set. Designed exclusively for CT4-V Blackwing models, this left and right pair refines the outer edges of the front bumper and wheel openings, creating a wider, more aggressive stance while preserving OEM design intent and aerodynamic balance.
Manufactured from real dry pre-preg 3K twill weave carbon fiber, each wheel arch is autoclave-cured to deliver motorsport-grade structural integrity, consistent weave alignment, and superior heat resistance. Compared to wet-lay or overlay carbon fiber alternatives, dry pre-preg construction uses reduced resin content and higher fiber density, resulting in improved strength-to-weight ratio and long-term dimensional stability — especially important in high-heat zones near front brake assemblies and airflow channels.
Styled after GM factory carbon aero components, these wheel arch extensions follow the precise curvature and contour of the CT4-V Blackwing front fascia. The subtle extension at the lower bumper corners enhances the visual transition between the front splitter and the wheel well area, creating a cohesive, performance-driven front profile without appearing overly aftermarket.
The high-gloss clear-coated carbon fiber surface features UV protection to guard against fading, yellowing, and environmental wear, ensuring the weave depth and finish clarity remain sharp over time.
Short Compatibility:
Fits 2020–Present Cadillac CT4-V Blackwing Sedan models only. Does NOT fit standard CT4 or non-Blackwing CT4-V models.
