Richard Muscat is contesting his third PIRTEK Enduro Cup with Garry Rogers Motorsport in 2019, and second with James Golding.
Having made his debut with James Moffat in 2017, the pair finishing seventh at Sandown, Muscat joined former Dunlop Super2 Series team-mate Golding last year.
The young combination kept their head at Bathurst, finishing a strong eighth.
Muscat also now tackles Lamborghini’s Super Trofeo Asia Series, following a pair of Super2 campaigns with GRM.
He finished eighth in the Super2 standings in 2016 and 10th in '17, having switched to Supercars from Porsches.
The Melbourne driver's career began in 2012, stepping out of go-karts and into the competitive Porsche 944 Challenge Series.
In his maiden year, Muscat took five of a possible seven pole positions, and recorded 13 race wins to become the first rookie to win the title.
His winning form continued the following year, moving to the Porsche GT3 Cup Challenge Australia.
Muscat added another title to his name, claiming the series and the prestigious Jim Richards Endurance Trophy.
In 2014, Muscat took his third series title in the Australian GT Championship, and the Sir Stirling Moss trophy.
That same year, Muscat won the Gulf 12 Hour, before joining the Porsche International Cup Scholarship and finishing sixth in Porsche Carrera Cup Australia in 2015.
