While waiting for my Unplugged Performance Front Lip & High Downforce Trunk Spoiler to arrive, I wanted to address the final component in the aerodynamics of the Model 3, which to me seemed to be the diffuser.
Now, as we know, Tesla has done a very good job with the stock underbody. It is effectively flat, and the rear diffuser already has a decent angle/expansion chamber towards the trailing end to convert low pressure into high pressure and create downforce. The one area that seemed to be lacking was vertical fins to reduce turbulent air.
Therefore, I set out to add vertical fins to the rear diffuser, in theory reducing the turbulent air and enhancing the positive affects of the diffuser. In the end, I think it looks well and should achieve the goal. When combined with the other aerodynamic bits, the affects should be compounded. The advantage to a diffuser as opposed to something like canards is it generally increases downforce without creating lots of drag (basically a solid downforce-drag ratio). Let me know what you think, photos attached!
