Aaren Russell joined forces with Andre Heimgartner in the PIRTEK Enduro Cup in 2018.
The pair raced together in 2016 with Lucas Dumbrell Motorsport, and Russell slotted in beside Heimgartner again at Nissan Motorsport.
Russell won the co-driver sprint race at the RABBLE.club Sandown 500 in changeable conditions.
The sons of former V8 privateer Wayne Russell, Aaren and older brother Drew spent time in the Dunlop Super2 Series between 2007 and '15.
They also paired up to contest the Bathurst 1000 together in 2015 with the family-run operation, finishing 17th as a wildcard.
Aaren Russell then got a taste of the main game in the first half of 2016, as David Reynolds' Erebus Motorsport team-mate.
He returned after that mid-year split to contest the 2016 and '17 enduros, and three other events in the latter, with LDM.
Russell impressed as a teenager in Formula Vee in New South Wales in 2009, then joined Drew in an expanded Novocastrian Motorsport Super2 line-up.
His first podiums came in 2014, when Russell finished seventh in the points in an ex-Dick Johnson Racing Falcon.
