Description
Advanced Composite Specialties diffuser insert for the 2025 C8 ZR1 Corvette is 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.
Ships direct from the manufacturer. Estimated 2 week lead time.
