TOYOTA GR86 / SUBARU BRZ AT-M3 MOTORSPORT WING (HD EDITION)
The AT-M3 in its most capable configuration. Fitted from day one. The AT-M3, Fully Loaded This is the AT-M3 Motorsport Wing in its most capable configuration: the complete high-downforce package with the HD gurney flap and updated endplates fitted from day one. Everything the standard AT-M3 does, plus roughly 192N (43.2 lbs) of additional downforce for about 35N (7.9 lbs) of drag at 180 km/h (112 mph), at a fixed wing angle. If you're buying an AT-M3 for serious track work, this is the version to buy. How a Tab This Small Moves Numbers This Big The gurney flap is a small tab standing up at the trailing edge, and it punches far above its size. Air stacks up in front of it and rolls off the back into a pair of vortices that sit just behind the wing, acting like an invisible extension of its shape. The wing behaves as though it were more curved than it actually is. That's how a tab this small generates a gain this large: it changes what the air thinks the wing looks like in a very efficient way. The HD endplates attack a different loss. Air always tries to spill around the ends of a wing, leaking from the high-pressure side to the low. Every bit that escapes is downforce you paid for and didn't get. These plates are larger than the standard AT-M3 endplates and angled inward at the lower edge rather than sitting flat, sealing more of the wing's span so the pressure difference stays where it works. They also carry the outer ends of the gurney — the mainplane, gurney, and endplates work as one system, and in the HD Edition they arrive as one. Spend the Gain Your Way Where the extra load goes is up to you. The AT-M3's eight degrees of adjustment mean you can take the full gain as downforce, or trade some back for less drag and more straight-line speed, tuning the wing to your track, your setup, your driving. Construction Every component is prepreg carbon fiber, the same motorsport-grade process as every ADRO part, for an exact resin-to-fiber ratio that wet lay can't match. The gurney sits along the mainplane on 3M tape and attaches at each endplate. All mounting hardware is included. The most capable AT-M3 we build, ready to bolt on and go to work. See you at the track!
