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 through 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 GR Supra ARD Aero Package is the one of the first full systems to come out of that program.
The Front Splitter
Most front splitters are flat panels. They add some visual aggression, generate a modest amount of downforce at the nose, and leave everything else to chance. The ARD front splitter is designed around a different idea: that the front of the car isn't just a downforce source — it's the starting point of a complete aerodynamic strategy that has to be managed all the way to the rear diffuser.
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.
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.
Undervanes are 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 Supra'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 (in ADRO bumper configuration), the system generates 2148N (483 lbs) of downforce at 180 km/h, a 1618% increase over the GR Supra's stock 125N, with a gain of +2023N (455 lbs) and a 45/55 front-to-rear balance.
To complete the package, we recommend the ADRO AT-P1 Reverse Swan Neck Wing.
