Overview

The ACS Composite Rear Diffuser Fins are an exterior component designed for the Chevrolet C7 Corvette. These fins are crafted from PC Composite, a material developed to withstand impacts, scrapes, and heat distortion, making it three times stronger than ABS. They are painted in Carbon Flash Black to match the vehicle's original finish.

Show original supplier description

The ACS Composite Rear Diffuser Fins are designed to enhance the aerodynamics and appearance of the Chevrolet C7 Corvette Stingray, Grand Sport, Z06, and ZR1 models. These fins stimulate airflow and reduce turbulent air at the rear of the vehicle, improving undercarriage airflow and overall aerodynamics. They are painted in Carbon Flash Black, utilizing RPO code CFZ and paint code WA501Q, to seamlessly match the factory finish. The design utilizes OEM data to ensure a precise fit and finish. The package includes four fins, a template for accurate placement, installation instructions, and all necessary hardware. Installation is estimated at 15 minutes per side, with a difficulty rating of 2. These diffuser fins are compatible with the C7 ZR1 (2019), C7 Z06 (2015-2019), C7 Grand Sport (2017-2019), and C7 Stingray (2014-2019), including both Coupe and Convertible/HTC body styles.
