Chaz Mostert has been fined $3,000 for disobeying the end of race procedure with his victory burnout at the WD-40 Phillip Island 500.

The 25-year-old celebrated his first Virgin Australia Supercars Championship race victory since August, 2015, with a static burnout in the Turn 1 run-off area.

It went against instructions distributed to teams earlier in the weekend that static burnouts could not be performed.

The stipulation had been made following a request from the circuit’s management.

Subject to a brief stewards hearing post-race where the team admitted the breach, the punishment has been confirmed in this evening’s bulletin.

“Following the Race, the DRD conducted an investigation into an allegation that the Driver of Car #55, Chaz Mostert, disobeyed the End of Race Procedure by performing a static burnout,” it read.

“Following an admission to the breach, the Stewards imposed a Fine of $3,000, of which $2,000 is suspended until 31/12/17.”

Officials investigated the Turn 2 incident on the opening lap involving Nick Percat, Todd Kelly, Garth Tander and Jason Bright, with no rules deemed to have been breached.

A request from Shell V-Power Racing to investigate Simona De Silvestro for alleged blocking and failing to give racing room to Scott McLaughlin on the last lap was also undertaken and too resulted in a determination that no breach occurred.
