The Holden squad joined the championship in 1996 as a one-car squad.
In 1998, the team expanded to two cars, and two years after that, GRm claimed its biggest ever result with a stunning Bathurst 1000 win for Garth Tander and Jason Bargwanna.
The team later ran the Volvo program in Supercars between 2014 and 2016, before reverting back to Commodores from 2017.

Stanaway and young gun James Golding are the current full-time drivers for the team.
It’s expected GRM will continue to operate as a race team in other categories, including TCR Australia.
The team also ran the development of the new open-wheel category S5000, which debuted at Sandown last month.
More to come.
