The 1987 ADC was, unlike previous years, only held as a single race rather than a series of rounds and was run as a support category to the 1987 Australian Grand Prix in Adelaide.

While David had been hired to drive ahead of the season he requested to skip the first two races to prepare himself, Gregor Foitek taking the seat instead.

Brabham joined the Tom Walkinshaw Racing Jaguar team in 1991 and also in that year won the Spa 24 Hours driving a Nissan Skyline R32 GT-R alongside Naoki Hattori and Anders Olofsson.

The S941 chassis was overweight, used a fully manual gearbox as opposed to the semi-automatic types used by most teams and inferior wire-spring Cosworth HB customer engines.

Traditionally the other team driver would withdraw in such a situation, but seeing the demoralisation around him, Brabham decided to race on, only to crash out after a suspension failure of his own.

In Ratzenberger's memory the team made a collective decision to see out the season, with Brabham's strong leadership often cited as a key factor.

While the Simtek was uncompetitive he won considerable acclaim for his determination and for gradually improving the speed of the underfunded package, also handily out-performing his various teammates.

Brabham quit Formula One at the end of that year to begin touring car racing – while he wanted to help Simtek the salary offered by the BMW works team was too good to ignore.

Driving a BMW 320i at Bathurst with brother Geoff, the pair were flagged in 2nd but were elevated to the win soon after the finish when their BMW Motorsport Australia teammates Paul Morris and Craig Baird were disqualified, the team making an error at the last pit stop by not doing a driver change and leaving Baird in the car for the run home, not realising that he would exceed his allowed driving time before the race ended.

Brabham joined Sumo Power GT for the 2011 FIA GT1 World Championship, teaming with Jamie Campbell-Walter in a Nissan GT-R.

Since 1999 he has been a regular in the American Le Mans Series (ALMS), having raced for teams such as Panoz and Prodrive Ferrari 550 Maranello.

At the 2006 24 Hours of Le Mans, Brabham scored a fourth in the GT1 category (ninth overall) driving for Russian Age Racing.

David Brabham became only the fourth Australian driver to win the 24 Hours of Le Mans following Bernard Rubin in 1928, Vern Schuppan in 1983, and older brother Geoff in 1993.

The initial start-up of the project was run via crowdfunding[5][6] through the Indiegogo portal, where members of the public and fans alike could become part of the team.

"Our complete focus is now on finding and signing the investors and partners that will be vital in securing the investment required to make this vision a reality.

Lisa Brabham (née Thackwell) was born in 1964 or 1965 in New Zealand and moved with her family to Perth, Western Australia at an early age.
