Couldn't load pickup availability
The RM Engineering GT4+ RS roof fin follows the A90/A91 Supra roof and rear-glass centerline in two sections. It was developed as part of the GT4+ EVO rear aero configuration, upstream of the rear wing.
Design and construction
Its design objective is to limit lateral roof flow and organize the air approaching the wing under yaw. Complete-package CFD context should not be treated as an isolated roof-fin downforce claim.
Product details
- Two-piece centerline configuration
- Supra-specific roof and rear-glass contour

Product FAQs
Does the Roof Fin include the rear wing?
No. This is the two-piece fin. The Supra GT4+ wing is a separate assembly.
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.
