        			The C7 Corvette combines style, purpose, and performance in all aspects. However, the Corvette&apos;s diffuser lacks that extra little something. At ACS, we make it our mission to develop those &#x2018;little somethings&#x2019; that can provide the difference between &#x2018;almost&#x2019; and &#x2018;absolute&#x2019;. 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. 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. Application Guide: C7 Z06 C7 Grand Sport C7 Stingray

## Features

- EASY INSTALLATION: A quick add-on modification that can completed in under an hour. Installation involves drilling (3) holes per fin. Template is included to guide you through the process as well as the necessary hardware. Securing the fins with bolts is optimal for performance.

- OPTIONAL CARBON FLASH PAINT: Painted in a carbon flash metallic black to match the trim pieces found on the C7 including the rear diffuser, hood and fender inserts.
- IMPROVED AERODYNAMICS: The addition of fins on the diffuser enables the air that passes underneath to flow unilaterally. This is optimal for airflow management has consistency is important for enhancing aerodynamics.

    Looks Great
  

*by C***J on Reviewed in the United States on August 1, 2019*









  
  
    very nice, install wasn't very hard.I just have 20inch arms so it was a little harder for me to get my arm up in the rear to get screws started on higher points, but still only took about a hour to install.
  


### ⭐⭐⭐ 







  
  
    Geat looking on my 2019 Vette.
  

*by A***R on Reviewed in the United States on May 6, 2019*









  
  
    I had fit issues with the right and left inner fins still not fitting tight at the top, great paint and finish on fins.Would have been smart if ACS had included a ratchet wrench with the kit to deal with the poor access onthe left side of bumper.
  


### ⭐⭐⭐⭐⭐ 







  
  
    Fairly easy to mount if you consider yourself a handy man
  

*by C***O on Reviewed in the United States on May 7, 2018*









  
  
    Fairly easy to mount if you consider yourself a handy man.  Took me about an hour to measure, drill and anchor them down.  The top screw on the far left and far right fins were the most challenging to get tightened due to the tight space behind them.
