Fabian Coulthard will not join team-mate Scott McLaughlin on the front row for the opening race of the WD-40 Phillip Island 500, after being excluded from qualifying.
Coulthard set the second-fastest time in ARMOR ALL Qualifying earlier on Saturday, behind the sister Shell Ford of Scott McLaughlin.
He has, though, been excluded from the session for a technical breach with his Falcon’s rear wing and will start the 57-lap race from the rear of the grid.
“A genuine error was made when a change happened in session,” Shell V-Power Racing managing director Ryan Story told Supercars.com.
“I accept responsibility and whilst it made no difference to the performance of the car, we’ve taken our medicine.
“Unfortunately that means Fabian will start last for this afternoon’s race.”
Coulthard’s exclusion promotes championship leader Jamie Whincup to start alongside McLaughlin.
The other Triple Eight Commodores of Shane van Gisbergen and Craig Lowndes will share the second, with Rick Kelly and David Reynolds fifth and sixth.
Race 9 of the season starts at 3:45pm.
