Carl Breeze secured his first pole position at Thruxton since 2011 with a dominant effort in the Michelin Ginetta GT4 Supercup qualifying session.
Breeze topped the times throughout the decisive final ten minutes of the session, posting a best time of 1m 15.317s giving him the top spot by 0.371s.
Rising up the timesheets through the session to finish second fastest was Michael Caine, the JHR Developments racer securing his best qualifying performance of the season so far.
Jamie Orton finished off the top spot in qualifying for the first time this year, the championship leader edging out his HHC Motorsport team-mate Will Burns by 0.030s for third.
Tom Oliphant was disappointed with just fifth place on the grid, the Century Motorsport racer feeling he was capable of a time at least half a second quicker than he produced.
Oliphant’s team-mate Ollie Jackson just missed out on the top six, Bradley Smith snatching the spot by 0.075s, with Reece Somerfield, Mitchell Hale and Tom Wrigley completing the top ten behind.
On his one-off appearance in the Supercup, LMP3 racer Gaeten Paletou was left to settle for eleventh when a broken differential left him parked at the side of the track early on.
In the AM category, Osamu Kawashima took his first class pole position by 1.756s from Colin White, who has been joined this weekend by his brother, and Supercup debutant, Keith White. Fraser Robertson completes the field in fifteenth overall.
