Why This Upgrade Matters
Transform the front end of your CT5-V Blackwing with the same craftsmanship and technology used in motorsport-grade aerodynamic components. These upper bumper shell pieces are precision-built from pre-preg (dry) carbon fiber, autoclave-cured for maximum strength and minimum weight. Each section is CAD-scanned from OEM geometry to ensure factory-level alignment and gap consistency with the stock front bumper assembly.
