Product Details
The Ascension RR Rear Wing Gurney Flap is an optional add on designed for drivers who want to extract more performance from their rear wing without changing the overall setup of the car. Small in size but effective in function, the gurney flap increases rear downforce by improving how air flows off the back of the wing.
A gurney flap works by sharpening the pressure difference between the top and bottom surfaces of the wing. By adding a vertical lip at the trailing edge, airflow stays attached longer underneath the wing while pressure recovery at the rear improves. The result is increased downforce with a relatively small change to drag, making it a smart upgrade for track use.
For the Ascension RR Rear Wing, the gurney flap is shaped specifically to match the wing profile and width. This ensures consistent airflow across the entire span rather than creating uneven pressure or turbulence. When installed, it allows the wing to generate more rear grip without needing to run an aggressive angle setting.
This makes the gurney flap especially useful for drivers who are newer to track driving. It provides added stability and rear traction under braking and corner exit while keeping the car predictable and easy to drive. For experienced drivers, it offers another tuning option to fine tune balance based on track layout, speed, and driving style.
The gurney flap is most effective when paired with the higher angle setting on the Ascension RR Rear Wing, but it also delivers benefits at lower settings by increasing overall efficiency. Drivers running the full Unplugged Performance aero package will notice improved rear confidence and consistency during high speed sessions.
Constructed from carbon fiber to match the wing, the gurney flap maintains the same premium appearance and strength required for repeated track use. Installation is straightforward and fully reversible, allowing drivers to adjust their setup as conditions or goals change.
The Ascension RR Rear Wing Gurney Flap is a simple upgrade with a meaningful impact. Whether you are chasing lap times or looking for more rear stability, it provides an effective way to push your Model 3 aero performance further.
Protect The Finish Before You Fit It
Your gurney flap ships in exposed carbon fiber carrying a base coat only. If the bare weave is the look you want, give it a high-UV-protection clear coat or wrap it in paint protection film (PPF) before it spends its life in the airstream. Clear coat or paint is far easier to lay down while the flap is off the wing, and PPF can wait until the flap is mounted, as long as any adhesive has cured for 24 hours or more.
Day to day, wash it by hand with pH-neutral soap, keep polishes, compounds and solvent-based cleaners off the surface, and dry with a soft towel rather than a brush. Sun exposure is the real enemy of unsealed carbon, so park under cover when the car is sitting. Because the base coat is only a starting point for clear coat, paint or film, UV fading and other cosmetic changes on unprotected parts are not covered by warranty.

Does the Gurney flap fit wings other than the Ascension-RR?
No. The flap is shaped to match the Ascension-RR wing’s profile and span, so pressure builds evenly across the full width instead of creating turbulence at the tips. It is not a universal strip you trim to fit. If your car wears the UP Ascension-RR rear wing, the flap mounts to it; the listing sits in our 2024+ Model 3 carbon exterior range alongside the wing itself.
Should I add a Gurney flap or just run more wing angle?
They do different things. More wing angle buys downforce at the cost of drag. The Gurney flap raises downforce by improving flow attachment, with a relatively small change to drag. The two also stack: the flap is most effective at the Ascension-RR’s higher angle setting, and at lower settings it improves the wing’s overall efficiency. Start with the flap, then adjust angle at the track.
Which finish should I pick to match my wing?
The flap comes in gloss clearcoat or satin clearcoat over carbon fiber. Match whichever finish your Ascension-RR wing wears so the trailing edge reads as one piece. Both finishes cover the same carbon construction underneath. The choice is visual, not structural.
Is a Gurney flap worth it for a newer track driver?
Yes. Extra rear downforce makes the car more stable under braking and more predictable on corner exit, which is exactly where newer drivers build confidence. Experienced drivers use the flap as a tuning tool, matching rear grip to track layout and speed. If you are starting out, pair the hardware with seat time: our UP All Inclusive Private Track Day with Instructor pairs coaching with a full day of laps.
What does a Gurney flap actually do?
A Gurney flap is a small vertical lip fitted at the trailing edge of a wing. It sharpens the pressure difference between the wing’s upper and lower surfaces, so airflow stays attached longer underneath and pressure recovery improves at the rear. The result is more downforce for a relatively small drag penalty. On the UP Ascension-RR rear wing, that means added rear grip without touching the wing’s angle setting.
