The future of the GT300 team was called into question when the number 22 Mercedes, which shared veteran pairing Hisashi Wada and Masaki Jyonai, was involved in a major incident at Autopolis at round six last year.
With the car written off in the incident, the pair had to miss the last two races of the season at Motegi and Fuji Speedway.
But now R’Qs was able to source a fresh Mercedes chassis and both Wada and Jyonai gave it a shakedown during a track day at Suzuka on Saturday.
Wada and Jyonai, who will both turn 60 later this year, will enter their 12th consecutive season as teammates and extend their record as the longest partnership in the SUPER GT grid.
Yokohama will remain tire supplier while the team’s partnership with Arnage Racing will also continue.
Mie Prefecture-based group Arnage raced a Mercedes-AMG GT3 under its own banner in 2021 but has yet to announce its plans.
Last year, two-time GT500 champion Masataka Yanagida was recruited to join gentleman racer Masaki Kano, but the pair failed to score points, finishing 14th at Autopolis as their best result.
Wada and Jyonai managed just one top 20 finish last year, at the season opener in Okayama.
If Arnage continues to market his AMG GT3, Mercedes would be present in the four-car SUPER GT, with Goodsmile Racing and LEON Racing both having already confirmed their plans for 2022.
