We’re looking to test different wheel flare designs with two main objectives:
Our baseline test will use a generic wheel flare similar to the ones currently on the market. We’ll run the numbers and see how they perform.
RESULTS- check back for updates.
Depending on what the first test reveals, we’ll make some changes:

CFD Update: Overfenders vs. Stock Body
We're back with an update on our CFD testing—this time focused on overfenders. We tested a generic-style overfender design against a stock body to see how they affect airflow and performance.
The overfenders we tested were our design. They’re very simple—just a 1" flange that covers the tires, with an opening at the rear. Aside from that, they’re almost identical to what you’d find on the market today. We did include a small 1/8" lip for rivets or other mounting methods, just to ensure that the flange wouldn't negatively impact the airflow.
The test results were honestly pretty shocking.
Downforce increased from 1300 lbs to 1400 lbs. Most of that gain came from the front wheel arch area, where air was being evacuated more efficiently. The splitter also lit up, showing a noticeable improvement in front-end performance.

Out back, the diffuser responded well to the wheel flares, but only gained about 9 lbs of downforce—nothing we’d call substantial.
The downside? A drag increase of 36 lbs. That gives us a lift-to-drag ratio of about 2:1. In other words, very costly gains. Our goal is to get closer to a 10:1 ratio, so this setup is far from ideal in terms of efficiency.
where we saw drag 
Looking deeper, we spotted lift forming on the top of the front fender,
along with drag hot spots on the leading edge of the front overfender.
The rear overfender was also producing noticeable drag along the back edge.
We're still digging into ways to refine the design, and this is just the beginning. Stay tuned for more updates as we continue testing and optimizing!
