ACS C8 Z06 ZR1 Rear Diffuser Insert
Upgrade the rear profile of your C8 Z06 or future C8 ZR1 with the ACS C8 Rear Diffuser Inserts—designed for enhanced styling and aerodynamic performance. Say goodbye to the plain rear valence and add a bold, motorsport-inspired look with this premium diffuser upgrade.
Easy to install, this modification requires just four small holes to be drilled into the unpainted undertray and is completely reversible.
More than just a visual upgrade, the ACS Diffuser Insert improves aerodynamic flow by channeling high-speed air away from the undercarriage, reducing turbulence and increasing rear-end stability—perfect for performance-driven drivers.

- Enhance airflow through diffuser tunnels with a directional linear fin design
- Boost aerodynamics by reducing rear turbulence
- Reversible mod
- Painted in Carbon Flash Black for a cohesive OEM look or available in select body colors for added contrast
How it's made
Engineered specifically for the C8 Z06 and ZR1, each insert is digitally designed for a precise fit with the rear valence. Molded using injection-formed PC Composite and finished in Carbon Flash Black to match factory trim. Optional body-color finishes available upon request.
