Leon Camier continued to decimate the opposition during the final ViSK.com British Superbike practice session of the weekend at Thruxton, the championship leader smashing the lap record in the process.
The Airwaves Yamaha rider was dominant throughout the 50 minutes, holding a 1.4 second advantage with just over five minutes of the session to go before Karl Harris shortened the gap slightly to just over a second.
Recovering from his high-speed crash in second free practice, Harris was a comfortable second fastest, four tenths up on HM Plant duo Josh Brookes and Glen Richards, the pair helping Harris extend the Honda threat.
Ian Lowry continued his ascension up the order on the Relentless Suzuki in fifth, ahead of John Laverty on the Buildbase Kawasaki in sixth.
Michael Rutter followed in seventh, with Simon Andrews, Chris Walker and Stuart Easton rounding out the top ten. Gary Mason maintained his run as the top Mirror.co.uk Cup runner in 11th overall.
