Thank you @Crocfor posting the converted image.
The S3 has front and rear dual element wings that were custom made for the car with nine lives racing. We did a full 3d scan of the car to make sure everything would mount up properly and actually function as intended. It was a bit of an experiment given how little power these cars have and the need for it to overcome the added drag. End result dropped lap times over 2 seconds at multiple tracks after some tuning was done on wing angles and removing the second element on higher speed tracks.
Regarding the CSR's future, it will likely also get wings and though I wish I could use my existing set, they do not fit the width of the car or the current downward angle on the cage. Hopefully they will find their way onto another S3 soon. That said, I intend on doing a very similar setup on the CSR in the next year or two. Im hopeful the additional power will allow for even better results.
