The Commodore was also run in selected (mostly Victorian based) rounds throughout the 1989 Australian Touring Car Championship. For the 1989 Bathurst 1000, Rogers accepted an offer to drive Colin Bond's Caltex CXT Race Team's second Ford Sierra RS500 with Ken Mathews (the car was the Sierra that Tony Longhurst and Tomas Mezera had driven to victory the 1988 race). Rogers and Mathews failed to finish the race. In the early 1990s GRM turned its attention to the Calder Park Thunderdome and the AUSCAR series running a variety of Ford Falcons during the category's heyday (during the 1990s AUSCAR fields were dominated by the Holden Commodore). At first, Rogers drove the car himself alongside Paul Fordham. Garry slowly eased himself out of regular driving, putting Steven Richards in the seat. The team also secured a major sponsor in Valvoline along the way.
