The top four drivers in the Australian V8 Supercars championship have all been penalised after Ford's Will Davison joined a star-studded naughty list following the sport's American debut.
Davison was docked 25 championship points for reckless driving after an incident in which he slammed into Holden's New Zealand driver Scott McLaughlin during the fourth race in Texas, wrecking both cars.
Holden's Jamie Whincup, who won three races over the weekend, team-mate Craig Lowndes and the leading New Zealander, Fabian Coulthard, were also docked points.
But their 30-point penalties for jumping the restart in race three means little change to the championship picture as all the top drivers were penalised.
Whincup leads Lowndes by 142 championship points.
Davison slips to third 213 points adrift of Whincup, with Coulthard 50 points further back.
