Chaz Mostert will lose his front row grid berth after copping a three place grid penalty for Race 19 at the Coates Hire Ipswich SuperSprint.

Stewards deemed the Tickford Racing driver impeded Shane van Gisbergen at Turn 6 while the Red Bull Holden Racing Team driver was on a flying lap in Armor All qualifying.

Following an investigation officials have since handed down a sanction which will see Mostert demoted from second to fifth on the grid.

As a result, Race 19 will feature an all Shell V-Power Racing front row with Fabian Coulthard joining polesitter Scott McLaughlin.

The second row will be shared by Erebus Motorsport’s David Reynolds and Nissan Motorsport’s Rick Kelly.

Meanwhile, stewards have confirmed that Jamie Whincup has copped a $1000 fine, with $500 suspended until the end of the year, after he failed to exit pit lane wholly within the fast lane during Practice 3.

“Following a post-race DRD investigation and an admission by Car #1, Jamie Whincup of a Breach of Schedule B2 Article 6.6 (failed to exit Pit Lane wholly within the fast lane) the Stewards imposed a Fine of $1,000 with $500 suspended until 31/12/18,” read a stewards report.

Race 19 is scheduled to start at 1615 AEST.
