ACS C7 Corvette Rear Diffuser Fins

The ACS Composite Rear Diffuser Fins for the Chevrolet C7 Corvette Stingray, Grand Sport, Z06, and ZR1 is our answer to the lackluster Corvette valence. While the carbon flash black diffuser is meant to visually cut the Corvette in half, the large panel falls flat when it comes to performance.  

The double sided fin system creates channels for airflow to pass undisturbed while you are relentlessly pushing your Corvette. The smooth air flow will ensure you are always in control. The four fins provide an enhanced appearance to the rear of your C7 Corvette.

Features

  • Stimulate airflow in the integrated diffuser by redirecting the rear airflow in a linear direction, helping to improve airflow in the undercarriage.
  • Boost the vehicle’s aerodynamics as a result of a reduction in turbulent air at the rear end. The diffusers act to direct fast-moving air away from the undercarriage as it decelerates and expands.
  • Painted in Carbon Flash Black to seamlessly blend into your rear diffuser making it look stock.
  • Designed using OEM data to ensure a perfect fit and finish.

How many fins are included in this product?

This product is for two (2) fins per tunnel. This means you will receive a total of four (4) fins. Two for each side.


How do these install? Do I need to remove my diffuser?

No. You do not remove your diffuser. The fins are installed via 3 SEM screws that hold each fin in place. A template is provided to drill the necessary holes in the diffuser


Can I install these with two-way tape instead of drilling

We always advise against the use of two-way tape when installing aero parts, as there is always the risk of the item tearing off the car.


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.

X Unpainted Black Plastic:
An unfinished surface that will require a final sanding prior to painting. A great option for those looking to customize and/or paint the parts themselves or have a body shop handle the paint. Not intended to be installed as is on a vehicle.

Carbon Flash Black:
CFZ is a black paint finish with a silver metallic flake in the paint. From far it appears as a gloss black finish; however, upon closer inspection a silver metallic flake can be seen inside the paint finish. CFZ matches all C7 Corvette accent pieces on the Corvette including the fender insert, hood insert, front grill, rear diffuser, and more. Carbon Flash Metallic Black is highly recommended by us for any Corvette parts.
