A RED FLAGGED and wet-weather opening practice session has offered little in the way of a form guide as the Porsche Paynter Dixon Carrera Cup Australia returned to the VAILO Adelaide 500. 

South Aussie hope Max Vidau topped the abbreviated session which was held in pouring wet conditions.

His 1m35.2686s lap was some 15 seconds behind the Carrera Cup lap record on the Adelaide Parklands circuit, showing how challenging the conditions were.

Drivers completed no more than four laps in the session prior to a red flag flying for Simon Fallon, who found the wall at Turn 8 aboard his Bob Jane T-Marts Sonic Motor Racing entry.

Fallon was uninjured, with the team currently assessing the damage to his car post accident.

Callum Hedge ended the session second outright – 0.09 behind Vidau – with Ryder Quinn and Bayley Hall next.

Dean Cook led the way in the SP Tools Pro-Am, with fellow title rivals Sam Shahin and Adrian Flack next in the order.

The lone practice session was the only on-track activity for the championship in Adelaide on Thursday, though Friday will be a bumper day on track.

Action starts early with a second practice session at 8:05am, followed by Qualifying at 10:35 – with separate sessions for Equity One Pro and SP Tools Pro-Am to set the grid.

The Endurance Cup finale will then be decided with the race commencing at 3:25pm local time.

All three sessions will be shown live on Fox Sports 506 and Kayo Sport.

The two races on Saturday and Sunday will also be shown live on the Seven Network around Australia.
