These look too wide and high to be functional.


Is there any windtunnel or CFD testing on this? Or is it just a "looks" thing?

ACS,

Are you running any Winter Stella Storm sale/promotion on the double fin diffuser for those of us who will be stuck at home for couple days?

Default I like these more agressive diffusers

Ivan Tampi, expensive, but are differently head turners.

Installed my ACS Diffuser Fins today!

To ACS: awesome product with a few recommendations:

1-Apply a Color Code Sticker on each fin with "P" for Passenger side and "D" for Driver side Fins. I didn't realize until i installed fin on wrong side because it didn't fit correctly and probably oversight on my part but A sticker would be helpful and avoid my mistake by others.

2-Why not have the C-Clamps already on the Fin as I broke two of them trying to spread to attach to Fin and had to go buy replacement clamps.

This is not a criticism but a consumer feedback for possible consideration. Otherwise, I am very happy with the product and install templates provided. Oh

Thank you for the feedback, I have already shared these internally.

We will begin installing the U-nuts, and considering adding a note.

We do engrave on the back side, Driver / Passenger side.

Default U-Nuts and Note for Diffuser Fin Install Instructions

I noticed the engraving on back of Fins after the fact, so a bright colored note to separate passenger from driver side as well as already having the clamps on the Fin would be awesome. Thanks for being open to receiving constructive consumer feedback as that is what great companies do as continuous improvement!

I have never seen any wind tunnel testing done on these diffuser fins, but I would be curious if they have any performance effects. I think the vast majority of us who have installed these on our cars did it strictly for looks.

I loved my fins I added to my diffuser but I recently went to the full Carbon Fiber Diffuser with the attached fins. Awesome!
