The Davison brothers team up for the PIRTEK Enduro Cup this year, as Alex Davison partners younger brother Will for a third time.
Alex and Will raced together at Sandown, Bathurst and the Gold Coast in an Erebus Mercedes in 2014 and '15.
The elder Davison missed out on a co-drive in 2016 but returned for a handful of events last year with Lucas Dumbrell Motorsport.
A highly-experienced and successful Porsche driver, Davison is pairing his Supercars role with a GTE drive in the 2018/19 World Endurance Championship.
After racing Formula Ford, Davison made his name as a young driver with Porsche overseas, including in its Supercup on the F1 bill.
His focus shifted back to Australia with Carrera Cup and a maiden Supercars co-drive with Perkins Engineering in 2004.
A full-time berth in 2005 with Perkins turned into a nightmare, Davison splitting with the team before the end of the campaign.
The Melbourne driver continued to rack up Porsche rides around the world, and perform well in the enduros, over the coming years.
Stone Brothers Racing offered a second full-time chance in 2009, Davison spending three seasons with the team and finishing a best of 11th in '11.
He returned in 2013 with Charlie Schwerkolt Racing in a Tickford-run Falcon, before moving to Erebus to partner Will as a co-driver.
