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.

Features:

  • Functions as an add-on to the OEM diffuser.
  • Manufactured in highest quality ABS composite material. Same material as the diffuser already on your car.
  • Installs using 3 SEM bolts per side, with supplied printed templates.
  • Installation time is 15 minutes per side.

     

     

     

    How many fins are included in this product?

    This product is for one (1) fin per tunnel. This means you will receive a total of two fins. One for each side.


    If I buy two sets, then can I install all four (2 per side)?

    No. These will not install correctly as they are built to fit on a specific location of the diffuser. You can find the 4-fin version here.


    What finish should I get?

    We recommend the Carbon Flash Metallic black paint as this will match the color that your C7 diffuser is currently painted. This is the same color found on all the black accent pieces.


    Can I install these with two-way tape?

    ACS never recommends the use of two-way tape unless called for. The fins are secured in place via 3 SEM bolts per fin that will require drilling the diffuser. These are aerodynamic components, and by only using two-way tape can fall off the car in motion.
