Show original supplier description
This Carbon Fiber Rear Diffuser from Extreme Online Store is crafted to elevate the rear-end aesthetics of your 2005-2013 Corvette C6 with a race-inspired, aggressive look. Its aerodynamic design actively contributes to downforce and airflow management, which can help reduce rear-end lift during spirited driving or high-speed cruising. Its weave consistency and precise fitment allow it to blend seamlessly with factory body lines for a clean, professional integration. This direct-fit component utilizes OEM mounting points and includes all necessary hardware for installation, with an approximate installation time of 2 hours and requiring light to moderate mechanical skill. This rear diffuser is specifically designed to fit all 2005-2013 Corvette C6 models, including Base, Grand Sport, Z06, and ZR1 variants. Installation is straightforward, requiring no permanent modifications to the vehicle's bodywork.
