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.\u003c\/p\u003e\n\u003csection\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003csection\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003ch2\u003eThe Undervanes\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch2\u003eHow It Works\u003c\/h2\u003e\n\u003cp\u003eSix 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAs part of the complete ARD Aero Package\u003c\/strong\u003e, 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).\u003c\/p\u003e\n\u003ch2\u003eMaterial\u003c\/h2\u003e\n\u003cp\u003eAll 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.\u003c\/p\u003e\n\u003cp\u003eFor 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.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eVehicle Fitment\u003c\/strong\u003e\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003cul\u003e\n\u003cli\u003e2023+ BMW G87 M2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNot sure it fits?
