HKS Premium Body Full Kit GR SUPRA (with FRP GT wing) - 2020+ A90 Supra
HKS Premium Body Full Kit GR SUPRA (with FRP GT wing) - 2020+ A90 Supra
HKS Premium Body Full Kit with FRP GT Wing for the 2020+ GR Supra
The HKS Premium Body Full Kit for the 2020+ Toyota GR Supra is HKS's complete exterior transformation for the A90 platform, including the FRP GT wing. The kit takes the Supra's already aggressive factory design and develops it in a track-focused direction. The GT wing provides meaningful rear downforce at speed, the front and side aero components balance the front-to-rear aerodynamic load, and the overall package gives the car a visual presence that reflects the engineering behind it.

- Front bumper, side skirts, rear diffuser, and GT wing
- Aerodynamically developed by HKS
- FRP construction for the wing, polypropylene for body panels
- Fitment: 2020+ Toyota GR Supra (A90)
Complete Kit Downforce: Approximately 80 kg at 200 km/h
The complete Premium Body Kit with FRP GT wing is the most aerodynamically comprehensive exterior package HKS produces for the A90 Supra. HKS's published figures for the complete kit show approximately 80 kg of total downforce at 200 km/h, approximately 25 kg front and 55 kg rear, providing a rear-heavy aerodynamic balance appropriate for the A90's rear-wheel-drive layout and rear-biased weight distribution. The GT wing alone accounts for approximately 40–45 kg of the rear downforce figure at that speed.
Front-Rear Aerodynamic Balance with the GT Wing
The FRP GT wing is the centerpiece of this kit. FRP (fiberglass reinforced plastic) gives the wing the structural rigidity needed to maintain its airfoil profile under aerodynamic load at highway and track speeds. A flexible wing loses efficiency as it deforms under pressure. The wing is mounted at a height and angle that HKS calculated for the Supra's aerodynamic balance in conjunction with the front aero components.
Paint, Professional Install, and FRP Notes
The full body kit components require painting before installation. The FRP wing arrives in a primer-ready state and body panels in polypropylene are primed and painted to match or contrast with the factory exterior color. HKS provides fitment documentation for all pieces. Professional installation and paint work is recommended for the full kit.
The FT Breakdown
The HKS Premium Body Kit is for A90 Supra owners who are building the car with purpose. It is not a styling kit. The GT wing works, the front aero works, and HKS's engineering history backs both claims. If you are on this page, you already know what a serious GT car looks like. This is what it looks like in HKS's language. Eighty kilograms of total downforce at 200 km/h with a 25/55 front/rear split means the GR Supra's rear tires are being loaded by aerodynamic force roughly equivalent to a medium-sized passenger in the back seat — except that force scales with speed rather than remaining constant. At a genuine track speed the numbers are higher and the effect on stability is proportionally larger.
