Jason Plato secured another pole position for MG at Silverstone as Dunlop MSA British Touring Car Championship points leader Gordon Shedden could only struggle to 19th spot.
Plato's fifth pole of the year came after he broke the qualifying lap record with a lap of 58.717secs at the wheel of his MG6 GT to outpace the Vauxhall Vectra of Dave Newsham.
Newsham however would be stripped of his quickest time post-session for running wide and dropped down to fifth, putting Mat Jackson's Ford onto the front row.
While Plato enjoyed his session, it was harder for title rivals Matt Neal and Shedden, with Neal only tenth and Shedden nine spots further back.
“Gordon only 19th – that's a shame, isn't it?” Plato said. “You shouldn't wish ill on your rivals… but I do. Hopefully the conditions will stay dry for tomorrow because clearly we're in great shape and a good points haul will really make this championship come alive for us.
“Things have a way of evening themselves out and maybe here it's our turn after some bad luck.”
Shedden by contrast was just glad to see the session draw to a close.
“We knew this was going to be our bogey circuit but we didn't expect it to be this bad – the pace simply isn't there,” he said. “As the championship leader I've also got to start the first race tomorrow carrying maximum success ballast in my car. The only positive from that session is that it's over.”
Jackson's run to second on the grid came despite his car being damaged in the second free practice session, with the Redstone Racing team carrying out repairs in time for qualifying, while Frank Wrathall and Rob Collard share row two. Newsham is then joined on row three by the Proton of Dan Welch.
Elsewhere, the returning Chris Stockton was 21st quickest in the Thorney Motorsport Vauxhall Insignia but has had to stand down from his drive due to illness and will be replaced by Tony Gilham.
