TOYOTA GR SUPRA ARD PREPREG RACE SPLITTER (ADRO BUMPER)

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 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.

How It Works

Upper vanes condition the airflow over the outer splitter surface, creating and powering the vortices under the splitter endplate tunnels. Lower strakes control outwash across the splitter, preventing spillage and maximizing effective working area. The F1-inspired endplates initiate strategic vortex generation down the car's sides, working with the V2 sideskirts to extract more air and drive more flow under the front end.

The raised central section feeds directly into the six mid-floor undervanes and delivers clean, conditioned flow to the rear diffuser, while significantly reducing pitch sensitivity, so the car's aero behavior stays predictable when braking, accelerating, or running over elevation changes on track.

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.

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.
