Nissan’s GT300 lineups revealed

Nissan’s GT300 picture is suddenly much clearer: car No. 62 will be HELM MOTORSPORTS with Yuya Hiraki and Reiji Hiraki, and car No. 360 will be TOMEI SPORTS with Rin Arakawa and Yu Kanamaru in Nissan GT-R NISMO GT3 machinery. (supergt.net 1) (supergt.net 2) Super GT splits its field into two classes, and GT300 is the class where many different brands and team budgets share the same track under balance rules that try to keep a Porsche, a Mercedes, and a Nissan in the same fight. Nissan is not running these cars as one factory squad; it is backing customer teams that each bring their own crew, setup choices, and race strategy. (supergt.net) (nismo.co.jp) The car in both entries is the Nissan GT-R NISMO GT3, which is the racing version of the road-going GT-R and uses a 3.8-liter twin-turbocharged V6 engine. In GT300, that car is an old, well-known tool rather than a mystery box, so results often come down to drivers, tires, and clean execution over a season of seven domestic races. (supergt.net) (youtube.com) The No. 62 car is the more personal story because HELM MOTORSPORTS is built around Yuya Hiraki, and his new teammate is his younger brother Reiji Hiraki. Super GT’s official site lists Yuya as driver and team representative, while a 2025 series report said Reiji moved up from a third-driver role to race alongside him. (supergt.net 1) (supergt.net 2) That matters on race weekends because GT300 races are shared drives, so one car’s result depends on two people handing the same machine back and forth through traffic, tire wear, and pit timing. A brother pairing can remove some of the usual adjustment period, because both drivers already know the team’s habits and the car’s baseline. (supergt.net 1) (supergt.net 2) The No. 360 car is a bigger reset. In 2025, TOMEI SPORTS listed Takayuki Aoki, Rin Arakawa, Hironobu Shimizu, and Atsushi Tanaka around the same GT-R, but the 2026 entry now centers on Rin Arakawa and Yu Kanamaru under the RUNUP × SOL name. (supergt.net) (supergt.net) Yu Kanamaru’s move is the part rival teams will notice first, because he was listed in 2025 qualifying results with Nissan’s No. 56 KONDO RACING GT300 car. That means Nissan has shifted an experienced GT-R driver from one supported entry into another, which usually happens when a manufacturer wants a smaller team to gain a steadier benchmark. (supergt.net) (nismo.co.jp) Nissan’s 2026 motorsports program says it will keep providing technical support to teams racing the GT-R NISMO GT3 in Super GT’s GT300 class. That support does not erase the gap between teams, but it means HELM MOTORSPORTS and TOMEI SPORTS are not developing these cars alone when they chase setup, reliability, and parts through the season. (nismo.co.jp) So the shape of Nissan’s GT300 campaign now looks like this: one family-run entry in No. 62 betting on continuity, and one No. 360 entry betting on a refreshed pairing with Arakawa and Kanamaru. In a class where the same car can finish in the midfield one week and fight near the front the next, those pairings are the closest thing to a map before the racing starts. (supergt.net) (supergt.net)
