How much downforce does the ADRO G82 M4 AT-R3 Swan Neck Wing V2 make?

ADRO quotes over 277.7 pounds at 110 mph from the dual element profile, which is what improves rear stability and grip at speed.

What is different about the V2?

The endplates. V2 uses flat, angular plates instead of the original curved design for a sharper look. The mainplane and mounting geometry are unchanged, so the difference is visual.

Does it fit the M440i?

Yes. ADRO lists this wing for both the 2021 and later G82 M4 and the G22 M440i.

Why prepreg carbon instead of aluminium?

It is around 45% lighter than a comparable aluminium wing, and the weight saved is at the very back of the car where it matters most. Prepreg also holds its profile under aerodynamic load rather than twisting and giving away the set angle.

Can I convert my existing AT-R3 rather than buying this?

Yes. The flat endplates are sold separately as AU-R16S and swap onto an existing AT-R3 using the same mounting points.

How quickly does it ship?

ADRO lists the ADRO G82 M4 AT-R3 Swan Neck Wing V2 as shipping within one to three business days. Contact us if you need a firm date before ordering.

Description

ADRO AT-R3 Prepreg Carbon Swan Neck Wing V2 for G82 BMW M4 and G22 BMW M440i

The ADRO G82 M4 AT-R3 Swan Neck Wing V2 comes out of ADRO’s Formula 1 inspired aerodynamics programme and is the version fitted with flat endplates rather than the original curved design. The dual element profile generates over 277.7 pounds of downforce at 110 mph, and the prepreg carbon construction makes it roughly 45% lighter than a comparable aluminium wing, so the load arrives at the rear axle without a weight penalty at the worst possible place on the car. It fits the G82 M4 and, usefully, the G22 M440i as well.

Flat Endplates, and What Changes

On the ADRO G82 M4 AT-R3 Swan Neck Wing V2 the V2 designation refers to the endplates. Where the original AT-R3 carries a curved outer edge that softens the wing against the rear of the car, the V2 runs a flat, angular plate for a sharper silhouette closer to a purpose-built race wing. The change is visual rather than aerodynamic; the mainplane, the mounting geometry and the angle of attack are unchanged, so this is a choice about how the car should look rather than how it performs. Existing AT-R3 owners can swap to the flat design separately with the AT-R3 flat endplate set.

Swan Neck Mounting and the Dual Element

The wing hangs from its uprights rather than sitting on them, which keeps the underside of the mainplane clean. That surface is where a wing generates most of its load, and conventional pedestals push into exactly the flow you want to preserve. The dual element arrangement then adds a second, smaller aerofoil behind the mainplane, letting the assembly carry more total camber before the airflow separates than a single element of the same aggression could manage.

ADRO G82 M4 AT-R3 Swan Neck Wing V2 Construction

Every AT-R3 is laid up in premium prepreg carbon fiber with machined aluminium uprights carrying the load into the trunk lid. On a loaded aerodynamic surface prepreg is a stiffness decision rather than a cosmetic one: a wing that twists under load gives away the angle it was set to, and the consistent resin-to-fiber ratio is what keeps the profile holding its shape at the speeds where that 277.7 lb figure was measured.

Notes

The V2 differs from the original AT-R3 only in its flat endplates. The mainplane, mounting geometry and angle of attack are identical
Already running an AT-R3? The flat endplate set (AU-R16S) converts an existing wing without buying the whole assembly
Sold as a complete wing assembly. The trunk lid is not modified, the brackets use the factory shut line
Professional installation of the ADRO G82 M4 AT-R3 Swan Neck Wing V2 is recommended. For fitment questions on your car, contact us.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
