Leon Camier continued to dominate proceedings at Donington Park following second free practice, the Airwaves Yamaha rider being joined up front for the first time this season by team-mate James Ellison.
The championship leader lowered his time from the morning to produce the only lap to dip below 1min 32secs, Camier taking full advantage of his new specification engine to lead the way by four tenths.
Having had technical issues in the morning, Ellison recovered to join his team-mate at the front of the field for arguably his best showing of the season so far, a sentiment that can be shared by third place man Simon Andrews on the increasingly competitive MSS Colchester Kawasaki.
Josh Brookes was also a surprise contender in fourth position on the HM Plant Honda having steadily worked his way into contention, his team-mate Glen Richards behind him in sixth with Chris Walker splitting the pair.
Camier's closest rival at the top of the standings, Sylvain Guintoli, had to make do with seventh, ahead of Stuart Easton, John Laverty and Ian Lowry.
