Corvette C6 Grand Sport Rear Diffusers

Explore Corvette C6 Grand Sport rear diffusers designed for all 2010–2013 Grand Sport models. This collection includes OEM-style replacements, extended lower valances, performance diffuser fins, full-width aero diffusers, and track-inspired rear panels engineered to enhance aerodynamics and rear-end styling. Available in ABS plastic, gloss black, matte black, primer-ready, fiberglass, and carbon-style finishes.

Each rear diffuser is engineered for precise Grand Sport widebody fitment, improving airflow management, rear-end stability, and overall vehicle aggression. Whether you’re restoring factory components or upgrading to a more performance-oriented design, our diffusers deliver OEM-level mounting compatibility with durable construction. For complementary aero upgrades, explore our C6 Grand Sport Front Splitters or C6 Grand Sport Aero Package.
