Cadillac ATS-V Factory Style Carbon Fiber Rear Bumper Diffuser Lip 2016-2019

Enhance the rear styling of your 2016–2019 Cadillac ATS-V with this Factory Style Carbon Fiber Rear Bumper Diffuser Lip. Designed as a direct replacement for the factory rear valance, this diffuser maintains OEM styling while introducing the aggressive visual appeal of exposed carbon fiber.

The factory-inspired diffuser profile preserves the ATS-V’s original bumper lines and quad exhaust layout while adding sharper contours and a more performance-focused appearance. This upgrade integrates seamlessly with the rear bumper to deliver a clean OEM-plus look suitable for both daily driving and performance builds.

Constructed from genuine 3K twill weave carbon fiber, the diffuser offers excellent strength and lightweight durability. The exposed carbon fiber weave provides a premium motorsport-inspired finish while maintaining the structural rigidity expected from high-performance exterior components.
