ADRO Racing Division Toyota GR Supra ARD Prepreg Race Splitter (ADRO Bumper)
Tax excluded. Shipping calculated at checkout
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.

What Is Your Return & Exchange Policy?
All processed orders that have not shipped will incur a 6% processing fee, this is mainly to cover any payment processing and cancelation fee with the manufacturer or warehouse. A processed order is an order that has already been put in our system and the product has been taken out of inventory and moving towards the packing and shipping face.
On special order or custom-made orders, the processing face is indicated when the manufacturer has received our order. Please be courteous and notify us ASAP if you wish to cancel any order(s) that were recently placed in order to prevent it from shipping out.
Due to the nature of racing and performance vehicles, no returns will be accepted on special order items, opened, installed, incomplete, or otherwise used products. If a product is ordered and not wanted, the UNUSED item can be returned within 30 days after the product has been delivered. This does not apply to SPECIAL ORDER items. Once the product is returned, you have two options for your refund:
You may have your purchase refunded back on your original payment method minus a 20% restocking fee of the total amount. In this case, please know that the initial shipping is not refundable (free shipping items still incur shipping chargers which MUST be deducted on a return). All items wanting to be returned MUST be reported within 30 days of delivery date. If you are still browsing and want an alternate product, we can provide you with a full credit minus shipping costs as a T1 Motorsports store credit. Some brands are excluded and may incur up to a 10% restocking fee. Please contact us to confirm.
On both refund options, a return shipping label may be provided if you are unable to ship the product(s) back using your own method of shipping. This shipping cost will be deducted from your total refund or credit.
