Long-time Chaz Mostert engineer Adam De Borre is moving on
Mostert and De Borre first linked up at DJR in 2013
Mostert/De Borre relationship has delivered 21 wins, including two Bathursts
Chaz Mostert has paid tribute to long-time right-hand man Adam De Borre, saying the departing engineer’s passion is “second to no one”.
The VAILO Adelaide 500 was the final event for the Mostert/De Borre relationship, which has yielded 21 race wins — including two Bathurst victories — across 10 years and three teams.
De Borre engineered Mostert when the driver debuted mid-season with Dick Johnson Racing in 2013, with the then 21-year-old driver taking a shock win at Queensland Raceway.
They combined at Tickford Racing between 2014 and 2019, with driver and engineer delivering a stunning last-to-first Bathurst victory in their first season with the Campbellfield squad.
Mostert and De Borre shifted to Walkinshaw Andretti United in 2020, and they duly delivered a second Bathurst triumph in 2021.
Come 2023, and Mostert will have a new voice in his ear in the form of Sam Scaffidi, who has been recruited from Tickford after a stint engineering James Courtney.
In one final act, De Borre helped Mostert steal fourth in the drivers' standings in the final race of the season from Will Brown.
“It will one hard to change,” newly-minted Barry Sheene Medal winner Mostert said of his De Borre relationship after Sunday’s race.
“We’ve won 21 races together, two Bathursts, we didn’t quite seal the championship together we wanted over the last 10 years, but I wouldn’t have done anything different.
“I’ve enjoyed my whole time racing with Adam, having him on the radio, trying to calm me down. It’s funny, my hair turns that colour when I’m in the car!
“I'm sure he’s throwing keyboards and stuff, but that’s what motorsport’s all about, his passion is second to no one.”
De Borre has worked in motorsport for over 20 years, and first started in Supercars with Garry Rogers Motorsport in 2006.
He is simply in need of a break from motorsport, and is keen to spend more time with his family and develop his business, AD Racing Shocks.
“We started this journey 10 years ago, and I didn’t expect it to be as long and successful as it has been,” De Borre said.
“Chaz has been great, we work together, we understand each other, and that’s a large part of it — it’s fun and enjoyable.
“I need to spend a bit more time at home, bit more time with the family, do some karting with the kids, and just slow down for a moment.
“I’ve been full-time in motorsport since ‘99, and I haven’t stopped. We speak about drivers being at ten tenths all the time, that’s how I am with Chaz between events.”
