“I’m super excited, obviously to get a co-drive, start my first Bathurst 1000 and make my main series debut is pretty cool,” Brown said.
“In 2016 I raced three categories, so it probably put three years into one.
“I stepped up into Super2 and did a good job, but I think doing so many categories over the last few years, and being able to adapt between different cars has helped me to jump into a Supercar and do a good job.”
Brown is expected to continue in Super2 with Eggleston Motorsport in 2018, having also finished fifth in Bathurst’s non-points 250km race for the class last October.
Following a test with Triple Eight last July, he will drive with Erebus for the first time later this month, when the team undertakes its maiden test day of the new campaign at Winton.
"Will has been a real standout talent in the recent years and particularly in his rookie Super2 season in 2017,” Erebus Motorsport general manager Barry Ryan said.
“We are very pleased to sign Will to drive his maiden Enduro Cup; he displays maturity above his years both on and off track.
"We look forward to seeing his driving talents first hand and being part of his development and growth."
While Youlden won Bathurst last year with David Reynolds, the team has opted not to make a definitive call on who will partner Reynolds and 2018 Supercars rookie Anton De Pasquale at Sandown, Bathurst and the Gold Coast.
