Tommy Hill is within just three hundredths of the Brands Hatch lap record as he and Swan Yamaha team-mate Michael Laverty moved to the head of the timesheets for second free practice.
The former World Superbike rider leapt to the top with just a few minutes remaining to displace long-time session leader Ryuichi Kiyonari, his effort of 45.499secs falling just shy of the lap record, held since 2007 by Gregorio Lavilla (45.460secs).
Laverty was another late mover to grab second on the second YZF-R1, himself just 0.008secs off his team-mate's pace.
Having topped the first two sessions of the weekend, HM Plant Honda had to contend with third and fourth, Kiyonari edging Shane Byrne, while John Hopkins kept himself well in the mix with a run to the fifth fastest time.
Dan Linfoot – a front row starter at Brands Hatch last year - produced another fine top ten performance to go sixth, while Loris Baz showed a marked improvement to end up eighth on the Motorpoint Yamaha, the Frenchman split by the two MSS Colchester Kawasakis of Stuart Easton and Gary Mason.
Josh Brookes rounded out the top ten, ahead of Tommy Bridewell and Michael Rutter, while Alex Lowes was fastest in the EVO category once again in 16th overall, ahead of PR Kawasaki's Simon Andrews.
