BMW G87 M2 (ARD)

Aero over aesthetic. Function over form. Purpose over compromise.

What is ARD?

ARD (ADRO Racing Division) is ADRO's motorsport engineering program, 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.

The Front Splitter

This isn't about adding a flat panel to the front end. It's about initiating a complete aerodynamic strategy, one that starts at the nose and has to be managed all the way to the rear diffuser. Every element of the splitter assembly is CFD-developed to generate, direct, and sustain the vortex structures that the rest of the ARD system depends on.

How It Works

Material

ARD components are produced in prepreg carbon fiber. Prepreg uses resin pre-impregnated into the fiber under controlled conditions, which means resin distribution is precise and consistent throughout the part. The result is a lighter, stiffer panel with no soft spots or resin-rich areas that can delaminate under sustained load.

For track use, this matters beyond aesthetics. A splitter that flexes under aerodynamic load does not produce the downforce it was designed to. Prepreg eliminates that variable. What the CFD predicted is what the part delivers, lap after lap, in heat and under sustained aero loads.

The Quad Canards

Canards are one of the most visually recognizable elements in motorsport aero. They are also one of the most misused. On most aftermarket kits, they are aesthetic additions that generate marginal front downforce and little else. The ARD quad canards are developed to do something more specific: manage the vortices initiated by the front splitter assembly and direct airflow around the front wheels.

How It Works

The front wheels are one of the largest sources of aerodynamic drag and turbulence on a road car. As they rotate, they throw air outward and upward, disrupting the clean flow that the splitter and undervanes depend on. The canards work to contain and redirect that disruption.

Each canard generates a vortex off its outer edge. Positioned in a quad configuration, those vortices are stacked and sequenced to build in strength as they travel rearward, creating a curtain of managed airflow between the front splitter endplates and the front wheel arches. This reduces the amount of turbulent, high-pressure air spilling inboard from the rotating wheel, which in turn keeps the underbody flow cleaner and the undervanes working at higher efficiency.

As part of the complete ARD Aero Package, the system generates 2555N (574 lbs) of downforce at 180 km/h, a 1254% increase over the M2's stock 189N, with a gain of +2366N (532 lbs).

Material

ARD components are produced in prepreg carbon fiber. Prepreg uses resin pre-impregnated into the fiber under controlled conditions, meaning resin distribution is precise and consistent throughout the part. The result is a lighter, stiffer component with no soft spots or resin-rich areas that can delaminate under load.

For canards specifically, stiffness is critical. A canard that flexes under aerodynamic load changes its angle of attack, which changes the vortex it produces and degrades the airflow management it was designed to deliver. Prepreg holds geometry under sustained load, so the canard behaves at lap 20 the same way it did at lap one.

The Undervanes

The component most aero kits ignore completely. The one that separates visual modifications from genuine aerodynamic systems. Most kits stop at the surfaces you can see: wings, splitters, canards. The underside of the car is where the most significant aerodynamic gains live, and it is where most kits do nothing at all.

How It Works

Six vanes are strategically positioned beneath the G87 M2's chassis to transform underbody airflow management. They generate large-scale vortices that dramatically increase suction on the lower surface, pulling the car toward the track with measurable force. Simultaneously, they direct airflow outboard, preventing stagnation under the center section and maintaining high velocity through to the rear diffuser.

The result is dramatic front and mid-section downforce increases without adding drag-inducing topside elements. These are gains that do not show up in photographs but show up immediately on a data logger.

Material

ARD components are produced in prepreg carbon fiber. Prepreg uses resin pre-impregnated into the fiber under controlled conditions, meaning resin distribution is precise and consistent throughout the part. The result is a lighter, stiffer component with no soft spots or resin-rich areas that can delaminate under load.

For undervanes, the material argument is straightforward. These components operate in a high-debris, high-heat environment on the underside of the car, exposed to road surface turbulence, brake heat, and sustained aerodynamic loading across an entire session. Prepreg carbon handles that environment without fatiguing. It also holds the vane geometry precisely, which matters because a vane that deflects under load generates a different vortex than the one it was designed to produce.

The Rear Diffuser

A diffuser works by taking the high-velocity, low-pressure air traveling under the car and gradually expanding it back to ambient pressure before it exits at the rear. Done correctly, this expansion accelerates the flow ahead of it, increasing suction across the entire underbody. Done incorrectly, or with gaps and interruptions in the undertray that allow turbulent air to mix in, the pressure recovery breaks down and the diffuser produces a fraction of what it should.

The ARD rear diffuser is developed as the endpoint of a complete underbody system, not a standalone component bolted to the rear bumper.

How It Works

The diffuser undertray seals the gaps that cause turbulent recirculation under the car. On a G87 M2, those gaps allow high-pressure air to bleed into the underbody from the sides and center, disrupting the low-pressure environment the diffuser depends on. Blocking them keeps underbody velocity high across the full floor, which means the diffuser strakes have clean, fast-moving air to work with rather than recovering from turbulence upstream.

The strakes inside the diffuser generate vortices that roll along the diffuser surface, energizing the boundary layer and preventing flow separation as the channel expands. This is what allows the diffuser to extract more work from the airflow without stalling. Those vortices are stronger because of what happens upstream: the ARD undervanes generate large-scale vortices that feed conditioned, high-velocity flow rearward through the floor, arriving at the diffuser inlet with enough energy to drive the expansion process effectively.

As part of the complete ARD Aero Package, the system generates 2555N (574 lbs) of downforce at 180 km/h, a 1254% increase over the M2's stock 189N, with a gain of +2366N (532 lbs).

Material

ARD components are produced in prepreg carbon fiber. Prepreg uses resin pre-impregnated into the fiber under controlled conditions, meaning resin distribution is precise and consistent throughout the part. The result is a lighter, stiffer component with no soft spots or resin-rich areas that can delaminate under load.

For a rear diffuser, panel stiffness affects more than durability. A diffuser channel that flexes under load changes its expansion geometry, which alters the pressure gradient the strakes are working against. Prepreg holds the designed geometry at speed and under heat, so the diffuser performs consistently across a full session rather than degrading as conditions change.

The AT-M3 Motorsport Wing

The 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.

How It Works

Material

The AT-M3 is produced in prepreg carbon fiber. Prepreg uses resin pre-impregnated into the fiber under controlled conditions, meaning resin distribution is precise and consistent throughout the part. The result is a lighter, stiffer wing with no soft spots or resin-rich areas that can delaminate under sustained aerodynamic load.

For a wing operating at track speeds, stiffness is not just a durability consideration. A mainplate that flexes under load changes its effective angle of attack, which changes the downforce it produces and the balance it delivers to the driver. Prepreg holds geometry precisely across a full session, in heat and under sustained loading, so the wing behaves consistently from the first lap to the last.

Fitment

Designed for the G87 BMW M2. Compatible with the stock trunk. Modifications to the trunk lid required.

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 Same Mainplane, Working Harder

You already own the hardest part to get right: the AT-M3 mainplane. The HD upgrade takes that wing and makes it work harder: a gurney flap for the trailing edge and a set of updated endplates to replace your originals.

The result: at a fixed wing angle, roughly 192N (43.2 lbs) more downforce for about 35N (7.9 lbs) of drag at 180 km/h (112 mph). That's a serious step in rear grip from two components — no new mainplane, no new mounts, no starting over.
