Bragging rights will be on the line during the Carrera Cup Australia’s Rennsport Pro-Am round with seven V8 Supercars drivers joining the battle.

As revealed last week, Shane van Gisbergen, Lee Holdsworth, Michael Caruso, Garth Tander, Tim Slade, David Reynolds and Nick Percat are all set to join the grid.

The former four are all Carrera Cup Australia rookies, although the well travelled Van Gisbergen has raced various Porsches in the past, campaigning a GTLM-spec 911 as recently as January’s Daytona 24 Hour.

Like Van Gisbergen, Tander also has strong form in GT machinery, shining during various outings in Aston Martin, McLaren and Audi GT3 cars over recent years.

Slade is meanwhile a regular at the Carrera Cup Pro-Am event, lining up for his fourth consecutive appearance this year.

Reynolds and Percat however boast by far the most Porsche experience, having previously raced in the category full-time.

The former raced in the class from 2005, scooping the championship in his third year before moving to V8 Supercars.

Percat meanwhile ran a single season in 2013, finishing runner-up to Porsche master Craig Baird.

While the Pro-Am format leaves the co-drivers as major variables in the races, the qualifying battle between the V8 stars is set to be one of the highlights of the weekend.
