Product description
Aero over aesthetic. Function over form. Purpose over compromise.
What is ARD?
ARD is ADRO Racing Division, the company's motorsport engineering arm, aimed at cars that spend real time on track. ARD develops its parts the way race teams do: CFD simulation first, then track testing before release. ADRO's head of aerodynamics, Scott, comes from a Formula 1 development background and leads ARD's work. The G87 M2 ARD Aero Package is one of the first complete systems from ARD.
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.
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
All ARD parts are made in prepreg carbon fibre. Prepreg carbon comes with the resin already impregnated into the fibre in controlled conditions, so the resin is spread evenly through the whole part. That makes the part lighter and stiffer, without weak or resin-heavy patches that could 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.

Before you paint or fit it
Check the packaging label against your order when the part arrives, and do a full test fit before any paint or installation. Returns and warranty claims aren't accepted on parts that have been altered or are no longer new and resalable.

ORDER-IN & LOGISTICS
PRE-PURCHASE & SHIPPING FAQ
How does the order-in process work?
We verify live supplier inventory and issue a comprehensive written quote covering the part, current AUD pricing, GST, and tailored freight to your address (or free Stepney collection). Once you review and approve the quote and vehicle fitment is confirmed, your order is secured directly with our manufacturer allocation.
What are the estimated delivery times?
Typical delivery is 1 to 2 weeks for air freight sourced directly from verified European and international manufacturers. Active consignment tracking is maintained throughout transit until parts arrive at our Stepney workshop for collection, workshop installation, or dispatch to your door.
Can I pick up or have parts installed locally?
Yes. Free local collection is available from our Stepney workshop facility in Adelaide. We also offer professional in-house fitting, alignment, and calibration by European platform technicians. Simply select "Supply and fit at Stepney" when submitting your enquiry.
What happens if fitment is uncertain?
Our workshop technicians cross-reference manufacturer technical schematics, platform codes (such as S58, B58, S63TU), and your vehicle registration or VIN before placing the order. If there are model-year variations, aftermarket modifications, or clearance concerns, our team confirms compatibility with you and the supplier prior to commitment.
