Jason Plato topped both British Touring Car Championship free practice sessions on the Silverstone National circuit ahead of the penultimate round of the 2019 season.
The Power Maxed Racing Vauxhall driver ended the second practice run with a 57.413s lap, 0.13 seconds clear of next-best runner Dan Cammish (Honda Civic Type R), with the top 27 cars all lapping within a second of the benchmark.
The Silverstone circuit has been resurfaced this year, and lap times in both morning sessions were comfortably quicker than the existing qualifying lap record - a 58.078s set by Mat Jackson in 2015.
Cammish's Team Dynamics team-mate Matt Neal was third in a session that was dominated by front-wheel drive competitors, with Tom Ingram - recovering from an earlier misfire in his Toyota Corolla - and Chris Smiley heading the BMW 330i M Sport of Tom Oliphant.
The second run was uninterrupted, but a red flag was called with 10 minutes to go in first free practice as Rory Butcher ran over a shard of debris, picking up a left-rear puncture on his AmdD Tuning Honda Civic Type R and spinning.
At the same time, the Audi S3 of Mark Blundell stopped on the approach to Luffield.
Plato's benchmark time of 57.731s in that session was some 0.3s slower than his FP2 effort. Cammish also ended FP1 in second, having lapped 0.046s shy.
The top two in the points - Colin Turkington and WSR team-mate Andrew Jordan - had complained of understeer in the 3 Series during first practice.
Running with the second-highest amount of success ballast, Jordan was a late climber to seventh behind Oliphant in second practice, with Turkington only 18th.
Jake Hill, who became a BTCC race winner last time out at Knockhill, was eighth in his Audi S3 ahead of Adam Morgan.
Both Team BMR Subaru Levorgs of Ashley Sutton and Senna Proctor were black flagged for exceeding track limits.
Sutton did end second practice 10th, ahead of Butcher and team-mate Mike Bushell - who retains the second AmD Tuning seat as Sam Tordoff has opted to miss the remainder of the season.
Plato's Vauxhall Astra stablemate Rob Collard was 13th ahead of Proctor.
Returning driver Michael Caine - who has replaced Nicolas Hamilton at Motorbase - was 27th in his Ford Focus RS.
