Brabham, grandson of triple world champion Sir Jack Brabham and son of Le Mans winner Geoff Brabham, will drive the second LD Motorsport Commodore.

The opportunity arose when regular LD Motorsport driver Taz Douglas had to withdraw due to a family wedding commitment.

The Supercars call up comes almost a year since Brabham made his IndyCar race debut in the Indianapolis Grand Prix.

Twenty-three year-old Brabham was already scheduled to be in Perth during the Supercars weekend, competing in Robby Gordon’s Stadium Super Truck Series.

“Obviously this has all come together at the last minute and has been a bit of a surprise, but we will give it the best shot we can,” said Brabham.

“When Phil (Munday, car owner) rang to see if I was interested it was obviously from way left field, but exciting at the same time. Phil has a track record of supporting young drivers in the sport and this is just another example and I am looking forward to rewarding his faith in me.

“We had a test lined-up with one of the front-running Supercar teams last year, but unfortunately time beat us and we never got it done.

“I am under no illusions about the expectations this weekend, but if I can get a bit of exposure for LDM and get a few laps under my belt in a Supercar then it works for all the stakeholders.

"I will be out there with plenty of guys I used to race karts against so it should be cool.”

Team owner Lucas Dumbrell is thrilled to be able to give Matt Brabham his touring car race debut.

“Matt is obviously a very talented young driver and probably deserves to be in the IndyCar Series full-time given what he has done to this point,” Dumbrell said.

“To have a member of the Brabham family, which really is motorsport royalty in this country and abroad, is pretty cool.

“At almost any other round he would not even be in the country so it is a bit of a win-win and will hopefully brings the team and Matt plenty of attention.

“It will also be great to have a Brabham associated with the Repair Management Australia Commodore.”
