Couldn't load pickup availability
Choose flat BASE or contoured EVO endplates on the RM Engineering 1600 mm GT4+ rear wing for the A90/A91 Supra. Both configurations share the carbon mainplane, swan-neck uprights and vehicle-specific mounting system.
Design and construction
The swan-neck supports leave the lower mainplane less obstructed. EVO changes the endplate geometry and was developed with the RS roof fin in the complete rear aero package; package results do not isolate the endplates alone.

Fitment and specifications
| Specification | Detail |
|---|---|
| Application | Toyota GR Supra A90 / A91 |
| Material | pre-preg carbon fiber mainplane and endplates |
| Configuration | 1600 mm swan-neck wing, BASE or EVO |
This Pit Garage listing focuses on Toyota GR Supra A90 / A91. Confirm the model, installed body panels and existing modifications before purchase. Aftermarket panels and changed mounting points require separate assessment.
Configuration comparison
| Configuration | Endplate Design | Intended Use |
|---|---|---|
| Base | Conventional flat pre-preg carbon fiber endplates | Dual-purpose street and track builds |
| EVO | CFD-developed contoured 3D pre-preg carbon fiber endplates | Track-focused and Time Attack applications |
RM-reported CFD results
| CFD Result at 120 mph | Base | EVO |
|---|---|---|
| Integrated rear-wing downforce | 230.5 lbf | 248.6 lbf |
| Rear-wing drag | 33.0 lbf | 34.9 lbf |
| Aerodynamic L/D | 6.98 | 7.12 |
RM reports these component forces from a complete-vehicle CFD model solved at 100 km/h. Values shown at 120 mph use velocity-squared scaling; they are not a separate 120 mph simulation or measured track result. They do not represent an isolated part gain or a guaranteed axle-load change on your car. The Supra BASE/EVO comparison used a 0-degree geometric wing setting. EVO reflects the corresponding full package, including roof-fin interactions, rather than an isolated endplate test.
Installation and ownership
Professional installation requires measuring and drilling the rear hatch. Test-fit the complete assembly before drilling and seal all openings carefully. Check hatch condition and interference with existing spoilers before ordering.

Product FAQs
Is the RS Roof Fin included with the wing?
The roof fin is a separate product. Confirm your selected wing package and any additional aero components before ordering.
What fitment information should I provide?
Provide the chassis, model year, installed bumper or body-panel configuration and any existing aero parts. Vehicle names alone may not establish compatibility after modifications.
Do these specifications guarantee a performance gain?
Dimensions and construction identify the product. Aerodynamic results depend on the complete vehicle, part position, ride height and operating conditions; the listing does not guarantee a specific lap-time or downforce gain.
