WIX Racing's Adam Morgan moved to the top of the timesheets in Free Practice Two at Snetterton as the Mercedes A-Class driver fell shy of the qualifying lap record by only a tenth of a second.
FP1 pace-setter Colin Turkington also led the way in the second session for much of the 40-minutes of running, before a late flurry of qualifying simulations brought about a change to the order.
Light spots of rain fell as the action got underway, leading to Ashley Sutton running a few laps on the Dunlop BluResponse wet tyres. In truth, the circuit was dry and all runners were on slicks within five minutes and Jack Goff was the first driver to set a representative lap time.
The pace quickened as the circuit conditions improved but it wasn't until the final ten minutes where significant inroads were made.
Morgan set the pace and couldn't be caught, with MG Racing RCIB Insurance's Sutton slotting into second. Aron Smith backed up his FP1 showing with another sterling effort in the final session. The VW CC claimed two wins in the hands of Turkington at Snetterton last season, with the characteristics of the 300 layout clearly suiting the German machine, so Smith will be hoping that such form can continue this weekend.
Tom Ingram pipped Turkington by 0.001s to claim fourth, whilst championship leader Sam Tordoff completed the top six order.
Aiden Moffat proved the pace of the Mercedes A-Class with seventh, whilst Power Maxed Racing's Hunter Abbott impressed with eighth.
Reigning champion Gordon Shedden would rarely celebrate ninth place in any session but the Scotsman bounced back from a difficult morning. His FP1 running was blighted by problems before his Halfords Yuasa Racing squad produced heroics with an engine change ahead of the afternoon run. His Honda Civic Type R eventually exited the pit lane with the #52 completing seven laps before the finish.
Motorbase Performance's Andrew Jordan got the better of team-mate Mat Jackson to claim tenth.
Matt Simpson's Honda stopped out on track early on while Jason Plato and Josh Cook endured a difficult session - both languishing outside the top 20 when the chequered flag fell.
There was little doubting the overall pace-setter, however, as Morgan sent out a warning ahead of qualifying. "We're in good shape, but we'll see what happens this afternoon," he said. "I've wanted to win this championship for a number of years and that remains the target for this season."
