ACS C7 Corvette Diffuser Fin System 

The C7 Corvette combines style, purpose, and performance in all aspects. However, the Corvette's diffuser lacks that extra little something. At ACS, we make it our mission to develop those ‘little somethings’ that can provide the difference between ‘almost’ and ‘absolute’. 

The ACS Diffuser Fins are not only aesthetically pleasing, but they will also:

  • Improve the airflow of the integrated diffuser by directing the rear airflow linearly; thus, improving undercarriage airflow.
  • Increase the aerodynamics of the vehicle by reducing turbulent air at the rear. The diffuser directs the fast moving air from the undercarriage as it decelerates and expands.


  • Functions as an add-on to the OEM diffuser.
  • High quality RTM composite material finished in Carbon Flash Black to match the OEM diffuser.
  • Installs using 3 SEM bolts per side, with supplied printed templates.
  • Installation time is 15 minutes per side.
