John Briggs, a Queenslander who relocated to Adelaide in the early 1980s due to work commitments, drove a Repco Holden powered Matich A50 Formula 5000 to a surprise second place at the 1978 Australian Grand Prix held at Sandown Raceway in Melbourne.
Roberts had the Monza re-built by Adelaide-based company K&A Engineering for Briggs and he raced it in the Australian Sports Sedan Championship.
He later switched from the Monza to an ex-JPS Team BMW 318i Turbo in the Australian GT Championship, before moving back into open wheelers with a Ralt RT21 Formula Holden in 1989.
In 2002 the team expanded to three cars with Betta Electrical Fords for veteran Tony Longhurst and Brazilian open wheel driver Max Wilson.
Both drivers were replaced in 2003 with Paul Radisich and Dean Canto for the 2003 season but by August, Briggs had sold the V8 Supercar operation to British outfit Triple Eight Race Engineering, to establish an Australian arm of the race team led by Roland Dane, Derek Warwick and Ian Harrison.
