What is the difference between the ARD AT-M3 and the ADRO AT-R3 swan neck wing?

The AT-M3 is the motorsport wing developed specifically within ADRO's ARD (ADRO Racing Division) program for the complete ARD Aero Package. It is a traditional mount wing designed for maximum rear downforce with 8 degrees of angle adjustability across a wide range. The AT-R3 is ADRO's dual-element swan neck wing; a separate product available for the G87 M2 and G42 M240i that uses a swan neck upright configuration for minimized interference with flow over the wing's suction surface. The two wings are distinct products for different buyer priorities.

Why does a 1,650mm span matter compared to a narrower wing?

Span directly determines how much of the rear axle width the wing covers and how evenly the downforce is distributed across it. A narrower wing concentrates its loading at the endplate roots and allows the center section to contribute proportionally less. A 1,650mm span uses the full practical width of the G87 M2's rear, spreading load evenly across the axle and producing consistent rear grip distribution rather than point loading at the corners.

What does the 8-degree angle adjustment range allow the driver to change?

Wing angle directly determines the balance between downforce and drag. More angle produces more rear downforce and more drag; less angle produces less of both. On a circuit with long, fast straights, the drag penalty of high angle costs meaningful lap time. On a short, technical circuit with hard braking zones, more rear downforce builds rear confidence. Eight degrees covers that full spectrum from minimum drag configurations for high-speed circuits to maximum stability for technical tracks, without requiring a different wing for each.

Does the AT-M3 require trunk modification?

Yes. Installation requires modifications to the trunk lid. This is standard practice for a motorsport wing of this type and span; the mounting uprights require access through the trunk lid at specific locations. For any car being prepared for track use at this level, trunk lid modification for wing installation is an expected step in the build process.

What does the 2,555N downforce figure refer to?

That figure refers to the complete ARD Aero Package for the G87 M2 at 180 km/h; not the AT-M3 alone. The AT-M3 provides the rear wing element; ARD's design approach is to maximize front and floor downforce first through the splitter, canards, and undervanes, then use the rear wing to set the balance. The total package produces a 1,254% increase over the stock M2's 189N, with a gain of 2,366N (532 lbs).

Description

ADRO AT-M3 Carbon Motorsport Wing for G87 BMW M2

The G87 M2 is already a serious performance car. The AT-M3 is for drivers who want to extract more of that performance on track, with rear downforce that is measurable, adjustable, and developed to the same standard as the rest of the ARD lineup by ADRO’s motorsport engineering program. The AT-M3 generates meaningful rear downforce at speed, increasing rear grip and stability through high-speed corners and under hard braking. The wide 1,650mm span maximizes the wing’s effective working area, producing a broad, even downforce distribution across the rear axle rather than concentrating load at the mounting points. A narrow or short span creates high loading at the endplate roots and lets the middle section contribute less to total downforce than the geometry suggests. At 1,650mm, the AT-M3 uses the full width available to spread that load evenly; rear grip increases consistently across the axle rather than peaking at the corners.

What is ARD?

ADRO’s motorsport engineering program, ARD (ADRO Racing Division), is built for drivers who demand more from their car on track. Every ARD component is developed the same way motorsport aerodynamics are: CFD simulation and track-tested before anything reaches a customer. Scott, ADRO’s Head of Aerodynamics, brings an F1 development background to every ARD project. The G87 M2 ARD Aero Package is one of the first full systems to come out of that program.

Frequently Asked Questions

What is the difference between the ARD AT-M3 and the ADRO AT-R3 swan neck wing? The AT-M3 is the motorsport wing developed specifically within ADRO’s ARD (ADRO Racing Division) program for the complete ARD Aero Package. It is a traditional mount wing designed for maximum rear downforce with 8 degrees of angle adjustability across a wide range. The AT-R3 is ADRO’s dual-element swan neck wing; a separate product available for the G87 M2 and G42 M240i that uses a swan neck upright configuration for minimized interference with flow over the wing’s suction surface. The two wings are distinct products for different buyer priorities; the AT-M3 is the ARD program component, the AT-R3 is ADRO’s street/track swan neck offering.
Why does a 1,650mm span matter compared to a narrower wing? Span directly determines how much of the rear axle width the wing covers and how evenly the downforce is distributed across it. A narrower wing concentrates its loading at the endplate roots and allows the center section to contribute proportionally less. A 1,650mm span uses the full practical width of the G87 M2’s rear, spreading load evenly across the axle and producing consistent rear grip distribution rather than point loading at the corners. This is the same reasoning used in motorsport; the wider the wing relative to the car, the more evenly downforce is applied to both rear tires.
What does the 8-degree angle adjustment range allow the driver to change? Wing angle directly determines the balance between downforce and drag. More angle produces more rear downforce and more drag; less angle produces less of both. On a circuit with long, fast straights, the drag penalty of high angle costs meaningful lap time on those sections. On a short, technical circuit with slow to medium-speed corners and hard braking zones, more rear downforce builds rear confidence and allows the driver to brake later. Eight degrees covers that full spectrum; from minimum drag configurations for high-speed circuits to maximum stability for technical tracks, without requiring a different wing for each.
Does the AT-M3 require trunk modification? Yes. Installation requires modifications to the trunk lid. This is standard practice for a motorsport wing of this type and span; the mounting uprights require access through the trunk lid at specific locations.

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.
