2014-2019 C7 ACS Diffuser Fin 4 Piece Set - CARBON FLASH

The C7 combines style, purpose, and performance to produce one of the most aggressive cars on the road today. However, the Corvette's factory diffuser lacks that little extra something. The 2014-2019 ACS 4 Piece Diffuser Fin Set provides your C7 with aggressive, track-ready looks and performance.

The simple, bolt-on fins install in roughly 1 hour and provide your Corvette with improved airflow on and off the track to help your performance. These fins help reduce the turbulent airflow at the rear of the vehicle and directs fast moving air from the undercarriage as it decelerates and expands.

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.
