GT4+ Canards

The RM Engineering GT4+ Carbon Fiber Canards are vehicle-specific front bumper dive planes for the Toyota GR Supra A90 and A91. Supplied as a four-piece set with installation hardware, they were developed around the vehicle’s front bumper geometry and designed to complement the GT4+ Front Lip and Tunneled Front Splitter.

Positioned along the outer sections of the front bumper, the canards interact with the local high-pressure airflow around the front fascia. Their contoured shape is designed to generate localized aerodynamic loading at the front corners while guiding airflow outward around the bumper and front-wheel region.

For the intended integrated configuration, pair them with the Toyota GR Supra A90/A91 GT4+ Front Splitter Kit.

Full-Vehicle CFD Evaluation

The GT4+ Canards were evaluated within the complete full-vehicle aerodynamic package. Their individual contribution was not isolated from the front lip, tunneled splitter and surrounding package interactions.

EVO configuration CFD relative-velocity field around the Toyota GR Supra GT4+ canards, splitter and endplate

The matched-view relative-velocity fields show the canards operating in both the Base and EVO front configurations. Because the EVO configuration also includes splitter endplates and other package changes, the resulting airflow differences should not be attributed to the canards alone.

Installation

Professional installation is recommended to achieve consistent positioning across both sides of the front bumper.

Test-fit all four canards and confirm their alignment before drilling and securing them with the included hardware. Installation permanently modifies the front bumper.

Product Questions

What are canards or dive planes?

Canards, also called dive planes, are aerodynamic components mounted on the outer sections of a front bumper. They interact with local airflow and are used to generate localized aerodynamic loading near the front corners of a vehicle.

How many canards are included?

The product includes four vehicle-specific carbon fiber canards, with two components positioned on each side of the front bumper. Installation hardware is included.

Do these canards fit both the A90 and A91 Toyota Supra?

Yes. They are designed for Toyota GR Supra A90 and A91 models with the compatible front bumper. Fitment with aftermarket bumpers is not confirmed.

Can the canards be installed without the GT4+ splitter?

Yes. The canards are sold separately and may be installed independently. However, they were developed to complement the Toyota GR Supra A90/A91 GT4+ Front Splitter Kit as part of the coordinated front aero configuration.

Does installation require drilling the bumper?

Drilling is not strictly required, as the canards may also be secured with automotive-grade 3M mounting tape. However, drilling and using the included hardware are recommended for the most rigid and secure installation.

Is there an individual downforce figure for the canards?

No. The canards were evaluated within the complete GT4+ full-vehicle aero package. Their contribution was not isolated from the front lip, tunneled splitter and surrounding package interactions, so the published CFD results should not be interpreted as canard-only performance figures.
