Michael Caruso was being lined up to co-drive with Shane van Gisbergen at Triple Eight for the Pirtek Enduro Cup before Garth Tander’s surprise appointment, Speedcafe.com has learned.
It is understood the Kelly Racing driver was poised to join the factory Holden squad after being unable to secure a full-time deal to remain at the Braeside operation for the 2019 Supercars season.
Confirmation that two-time race winner Caruso will see his full-time Supercars career come to a premature end is expected to be announced shortly, alongside his plans for this season.
The 35-year-old has emerged as a top enduro signing given his strong 11 season career in the main game which began at Garry Rogers Motorsport in 2008.
He scored victories at Hidden Valley in 2009 and 2016 alongside eight other podiums, with his last arriving at The Bend Motorsport Park in August.
It is believed that Andre Heimgartner and Garry Jacobson remain favourites to secure the two remaining seats at Kelly Racing, alongside the already confirmed Rick Kelly and Simona De Silvestro at the Nissan squad.
