Professional Race Car Driver Dan Clarke Tests Various Wing Setups on an NA BRZ
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! Track Testing - Verus Engineering UCW Rear Wing vs. Verus Engineering High-Efficiency Wing vs. Competitor 250mm Rear Wing Driver's Dan Clarke Professional race car driver who has driven in many racing series:
Justin Green Average track car enthusiast and owner of the test car:
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.

The competitor wing was at a higher angle of attack, and had more peak downforce as well as average downforce with both drivers. Dans 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. |

One could argue that at the 5600 mark Dan Clarke carried too much speed into a turn (I don't know what turn that exactly would be at Putnam) and thus overdrove on entry and lost some time that way with the UCW vs High Efficiency Wing.
From my own testing - UCW performs pretty well between 3-6 AOA for my needs. Depending on the track, conditions, etc etc.

Is there a baseline lap time pre-aero, even just for Justin? I'm curious what each part contributes to shaving off time as well as a full package. It is nice to see the AOA can be considerably less on the UCW wing and produce good downforce.

Looks like Dan over did the entry at ~5400 too so he'd have been a good bit quicker on the UCW wing had he gotten that right
Thanks for posting the actual lap data! edit: I see someone else pointed it out too

Yes, Justin's best lap without aero was 1.25.997.

It's literally a name. No designation beyond that
