[Clay_from_Verus]

Hey all! Just wanted to introduce myself as a new member of the group. Some of you may know me as Clay from Verus as I run sales and marketing for Verus Engineering. I also have a 2013 Subaru BRZ as my personal track car.

As a new member of the group, I wanted to share some testing results regarding 3 different wing setups in conjunction with our Street Front Splitter with Race Upgrade, Splitter Endplates, and Rear Diffuser. The below information shows the differences in lap times between a professional race car driver, Dan Clarke, and a novice driver, Justin Green. We have been doing a bunch of testing at our local track and have more to share soon!

What is Being Tested?

We tested 3 different wings on the same day, with the same vehicle, the same drivers, and on the same track.

1. Competitor wing was tested at 10 degrees AOA with Gurney Flap
2. Verus Engineering UCW Rear Wing (1 degree AOA for Dan Clarke, 6 degrees AOA for Justin Green)
3. Verus Engineering High-Efficiency Rear Wing (12 degrees AOA for both)

The competitor wing was at a higher angle of attack, and had more peak downforce as well as average downforce with both drivers. Dan’s laps were more consistent, which means his values are closer to reality. What the data really shows is how efficient our wings are compared to the competition. The UCW Rear Wing, which was at 1 degree AOA, was producing a small amount less downforce than the competitor wing at 10 degrees, but much faster because it is an efficient design.

The most striking conclusion is that the amateur driver was faster with a more rear-biased aero-balance than the professional driver. For Dan, the High-Efficiency Rear Wing was the fastest setup while for Justin, the UCW Rear Wing was the faster setup.
