The fifth-generation Toyota GR Supra, developed on the A90/A91 platform jointly with BMW and assembled by Magna Steyr in Graz from March 2019, found a second life in Japanese motorsport almost immediately. Built to JAF-GT GT300 regulations and powered by Toyota's naturally aspirated 2UR-GSE 5.4-litre V8, the Saitama Green Brave GR Supra has been a fixture of the GT300 grid since 2020. Spark Model's 1:43 scale model of the 2025 season car is part of a dedicated lineup of 23 resin replicas covering the full 2025 Super GT GT300 field.
The GR Supra road car measures 4,380 mm in length with a 2,470 mm wheelbase — compact dimensions that translate well to the tight GT300 regulations. Under JAF-GT rules, the Supra's silhouette bodywork houses Toyota's 5.4-litre 2UR-GSE V8, a configuration distinct from the turbocharged units seen in FIA-GT3 machinery sharing the same grid. For the 2025 campaign, regulation-mandated updates were applied, and the car ran on Bridgestone tyres throughout the season.
Yoshida, Nonaka and a Sepang Podium
Saitama Green Brave traces its roots to Saitama Toyopet, a Toyota dealership group based in Saitama Prefecture, which founded the team in 2012. The green-dominant livery is a direct expression of that corporate identity. Hiroki Yoshida, born 21 December 1983, is the team's long-standing lead driver and the 2023 Super GT GT300 Drivers' Champion. For 2025, he was paired with TGR Driver Challenge prospect Seita Nonaka, born 25 October 2000 and a 2025 SRO Japan Cup GT4 champion. Despite a disrupted pre-season and a DNF at the Okayama opener, the pairing recovered to finish 3rd at Round 3 in Sepang on 28 June 2025 — their only podium — and ended the year 7th in the GT300 championship with 70.5 points.
Spark Model's 1:43 Resin Craftsmanship
Spark Model produced a series of 23 1:43 resin models covering every GT300 entry in the 2025 Super GT season. The #52 Saitama Green Brave GR Supra is rendered in resin — a material that allows sharp surface definition across the Supra's aerodynamic bodywork, including the wide-arch GT300 silhouette bodywork and rear diffuser assembly. As a resin model, the body is a sealed one-piece construction with no opening parts; surface and livery accuracy are where Spark concentrates the detail work. The model is listed at approximately 10 cm in length, consistent with a 1:43 reduction of the 4,380 mm road-car body.
In the Display Cabinet
At roughly 10 cm long, the model sits comfortably on a standard collector shelf without dominating the space, and the included display base and display case provide a ready-to-display solution straight from the box. Collectors building a complete 2025 Super GT GT300 grid will find the #52 an essential piece within Spark's 23-model lineup. It pairs naturally with the 2023 championship-winning GR Supra from the same team and the same number, creating a clear narrative arc from title triumph to the 2025 Sepang podium. The car also represents one of the final competitive seasons for the A90/A91 GR Supra in GT300 racing.
Frequently asked questions
How big is the 1:43 scale model?
The Toyota GR Supra road car measures 4,380 mm in length. At 1:43 scale, that works out to approximately 10 cm. The model fits easily on a standard shelf, and the included display base and case mean you need only a modest amount of display space.
Does the model have opening parts?
No. Like all Spark Model resin releases, the #52 GR Supra GT300 has a sealed one-piece body with no opening doors, bonnet or engine cover. Detail is concentrated on the exterior surfaces — the GT300 aero bodywork, livery graphics and wheel/tyre rendering.
Who drove the #52 GR Supra in the 2025 Super GT season?
Hiroki Yoshida (born 21 December 1983), the 2023 Super GT GT300 Drivers' Champion, and Seita Nonaka (born 25 October 2000), a TGR Driver Challenge prospect who also won the 2025 SRO Japan Cup GT4 title. The pair finished 3rd at the Sepang round for their best result of the year.
What is the connection between Saitama Green Brave and Toyota?
The team was founded in 2012 by Saitama Toyopet, a Toyota dealership group based in Saitama Prefecture. The green livery directly reflects that organisation's corporate colour. The team has campaigned the GR Supra in GT300 since 2020 and won the GT300 Drivers' Championship in 2023 with Hiroki Yoshida.
