Description
Made from lightweight .063/.080 5052 aluminum, our CFD-tested endplates are designed to improve the performance of your existing NLR airfoil. Available in both low drag, standard and high downforce configurations, they work to improve the efficiency of your wing by decreasing the strength of the tip vortices. 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. In the low drag configuration, the lower portion of the endplate is straight to allow for the gradual mixing of high and low pressure flows to reduce drag over a rectangular endplate of comparable area by as much as 10%. The high downforce bend incorporates the pressure relief slots above the wing for improved underwing efficiency, while also adding a full height vertical Gurney flap to increase the underwing suction and maximize low pressure flow under the airfoil. Both versions offer reduced drag over commonly used rectangular endplates, and it is also possible to pair either with our low-drag Serrated Gurney flap for even larger downforce gains of as much as 8% (depending on the wing angle of attack). Please allow 2 weeks for laser cutting, fabrication and coating + 3-5 days for UPS Ground shipments.
