The Corvette Stingray is a beautiful car on that we can all agree. It combines style with purpose and performance in almost every aspect. However, the C7 Corvette's diffuser just lacks that little something. Hence the reason so many manufactures have worked to upgrade this component. Advanced Composite Specialties makes it their mission to develop all those little somethings and find a solution that can provide the difference between almost and absolute.

ACS' purpose built RTM composite rear diffuser fins are not only aesthetically stunning, there's serious performance enhancements as well. The simple installation will not only improve the airflow of the integrated diffuser by directing the rear airflow linearly, thus improving undercarriage airflow - they will also increase the aerodynamics of the Corvette by reducing turbulent air at the rear. The diffuser directs the fast moving air from the undercarriage as it decelerates and expands. In short, the fins improve on what is already a high-performance design. Fits C7 Corvette Stingray, Z06 and Grand Sport models.

Check out these details of the C7 Corvette Stingray diffuser fins:

  • Can be installed on any C7 Stingray, coupe, convertible, Z06 or Grand Sport models
  • Functions as an add-on to the OEM diffuser
  • High quality RTM composite material finished in Carbon Flash Black to match the OEM diffuser
