Sam Tordoff took the upper hand in the second Dunlop MSA British Touring Car Championship practice session at Silverstone, leading a Triple Eight one-two.
Initial practice pace-setter Jason Plato again showed his speed in the opening minutes of the second 40-minute encounter of the day, moving to the top of the times as the first laps were reeled off.
The former double champion held the advantage for almost the entirety of the session, until the very final minute when team-mate Tordoff stole the top spot away with a lap time of 58.624s.
The time was just 0.199s quicker than Plato as Triple Eight MGs locked out the top two spots, heading into qualifying where Tordoff aims to make it three pole positions on the bounce after Knockhill and Rockingham.
Colin Turkington showed that he will remain a threat to the MGs by ending third in practice, ahead of the BMR Racing Volkswagen CC of Aron Smith, Turkington leading the series heading into tomorrow’s trio of races by 55 points from Plato.
Fifth was Mat Jackson – a four-time winner at Silverstone in BTCC – ahead of another VW CC, this time of Jack Goff, the former Renault UK Clio Cup champion again showing fine pace at the Northamptonshire circuit on Saturday.
Next up was Andrew Jordan, the reigning BTCC champion pipping Marc Hynes, Matt Neal and Rob Austin who all rounded out the top 10. The second Honda Yuasa Racing Civic Tourer of Gordon Shedden meanwhile could only manage 14th, ahead of Alain Menu.
Martin Depper was one of several drivers to come a cropper at Copse corner during the session, spinning his Pirtek Racing Honda Civic after almost gathering up a big sideways moment.
The Airwaves Racing Ford Focus of Fabrizio Giovanardi also found itself facing the wrong way at the first bend, while a West Surrey Racing BMW also found itself facing the wrong way at the same bend.
A brief red flag interruption was also caused by Warren Scott, while Aiden Moffat was back-flagged during the session.
