Brown will join former Super2 Series teammate Nathan Morcom as he joins the Sydney based team for the inaugural season of the TCR Series on Australian soil.
The 21-year old is one of only five drivers to achieve two National Circuit Titles in Australia in the same year, after winning both the Australian Formula 4 Championship and Australian Toyota 86 Series in 2016.
Brown is a recipient of the 2017 Peter Brock Medal and Mike Kable Young Gun Award, awarded to the best first-year driver across the Supercar Championship and Super2 Series.
Alongside racing with HMO Customer Racing in 2019, Brown will also continue to drive in the Super2 Series and will co-drive with Anton De Pasquale from Erebus Motorsport in the Supercars Championship Endurance Cup.
Despite a busy racing calendar, the 21-year-old is looking forward to racing under the HMO Customer banner for the upcoming TCR Australia Series.
