Based on our proven design for the NLR airfoil and make from lightweight .063/.080 5052 aluminum, these CFD (and wind tunnel) tested endplates are also being developed to improve the performance of the popular WingLogic 9.8” (250mm) chord airfoils. See the recent results of Occam’s Racer’s independent testing here: https://occamsracers.com/2026/06/10/occams-racer-endplate-test/
They work to improve the efficiency of your wing by decreasing the strength of the wingtip vortices. These areas of turbulence are present at the outer edges of all motorsport wings and are the result of the mixing of the high pressure air above and the low pressure air below. When these areas clash directly, it can lead to additional form drag caused by the large size of the downstream vortices & turbulence bubbles.
Adding pressure relief slots above the wing allows these two pressure zones to equalize more gradually, reducing the size of the wingtip vortices and the corresponding drag. Additionally, reducing the size and intensity of the wingtip vortices allows the underwing vortices to be stronger, drawing more air under the more powerful low-pressure side of the wing.
Our low drag option offers the highest efficiency (L/D ratio) offering similar performance and reduced drag over comparably-sized rectangular endplates. The high downforce bend incorporates angled trailing Gurney flaps to further enhance the flow beneath the wing, allowing the freer-flowing suction side to provide a greater increase in overall downforce. Even so, it’s worth noting that these endplates still produce drag comparable to similarly-sized rectangular endplates.
NOTE: This product is made to order, so please allow 3-4 weeks for laser cutting, fabrication, powdercoating and shipping.
