New Radon rear wing
We tested our new single element rear wing at Road Atlanta during the pro series race this past weekend. Phil Lombardi had some success using it, finishing sixth in the first race and third in the second race.
We are still digesting the data from the weekend, but results are consistent with our CFD analysis. At Road Atlanta it was worth just over 1 mph in top speed for equivalent downforce over our two-element design, or about 2 mph more than a conventional two-element (Van Diemen/Cooper style) wing. This was worth some lap time there, but the difference would be even more pronounced at a place like Road America or Watkins Glen.
Those benefits are based on real data and back-to-back testing, and supported by CFD and wind tunnel results. I'm an engineer, not a marketing person, or I would be claiming 5 mph!
The wing produces enough downforce to replace a two-element design run at lower angles of attack, roughly anywhere in the upper two-thirds of the adjustment range on most cars. I'm told Phil had the highest speed through Turn 1 of anyone, so obviously we are producing good downforce.
The cost is $790. We tried to keep the price low, but it's a complicated part with substantial internal structure and a tricky layup schedule.
