Large Time Attack Endplates (universal fitment)
Made from lightweight .063/.080 5052 aluminum, these CFD-tested endplates are designed to improve the performance of your existing 10-14” chord airfoil. Available in both standard and high downforce configurations, they work to improve the efficiency of your wing by decreasing the strength of the tip 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 size of the vortex/turbulence bubble.
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 beneath the more powerful low-pressure side of the wing.
In the Standard configuration, the lower portion of the endplate is straight to allow for the angular vortex mixing of high and low pressure flows, reducing drag over a rectangular endplate of comparable area by as much as 10%. Depending on the track and your car’s power to weight ratio, a lower drag configuration is sometimes the quicker way to go! (.080 sheet is used to add additional stiffness due to lack of vertical Gurney flap on low drag endplates)
The High Downforce Time Attack bend incorporates the same pressure relief slots above the wing for improved underwing efficiency, while the addition of angled trailing Gurney flaps further enhances the flow beneath the wing, allowing the freer-flowing suction side to contribute a greater proportion of the overall downforce.
It worth noting that both versions offer reduced drag over commonly used rectangular endplates, and it’s also possible to pair either with our low-drag Serrated Gurney flap (available elsewhere on our site) for even larger DF gains of as much as 8% (depending on the wing’s angle of attack.
NOTE: This product is made to order, so please allow 2 weeks for laser cutting, fabrication, powdercoating and shipping.
