As in the earlier session Porsches dominated the second practice for the Avon Tyres British GT Championship at Snetterton, Jon Minshaw and Tim Harvey's #33 Trackspeed car setting the best time of a session truncated by a red flag and then the weather.
The quintet of Porsches held the top five positions at one point in the session after Michael Caine and Benji Hetherington took their respective charges out on new Avon Tyres for the second half of the session. Caine, in the #10 car partnered by Daniele Perfetti Caine set a best time of 1:51.121, two tenths down on his P1 marker, and exactly the same time posted by Joe Osborne in the #32 Trackspeed Porsche. Only the Trackspeed man's having set the time fractionally earlier kept him in second place behind teammates Tim Harvey and Jon Minshaw.
After Minshaw drove in the early part of the session Harvey took over the race and with 40 minutes of the hour long session remaining lapped the three mile circuit in 1:50.922, becoming the only man to lap below 1:51 in the session.
The Porsche dominance was only broken by the RJN Motorsport Nissan GT-R, which claimed the fifth fastest time (1:51.853) for Alex Buncombe and Jann Mardenborough, relegating P1 pacesetters David Ashburn and Richard Westbrook to sixth fastest.
Through bumped down a spot by the Nissan's improvement Ecurie Ecosse stand-in Oliver Millroy bettered his own time by four tenths. However, Millroy was soon spinning on the infield of the track, the recovery of the BMW Z4 pulling out the red flag with twenty minutes of the session still to run.
With cars queued at the end of the pitlane in anticipation of the restart the weather took over, torrential rain advancing from the first corner at Riches down the pit straight, flooding the track and reducing the pitlane to a conduit flowing back towards the final corner.
Unsurprisingly, as cars were pulled or pushed from the line the session ended with another lap being completed.
As such Aaron Scott and John Dhillon of Scuderia Vittoria were the lead Ferrari in eighth, with United Autosports and Beechdean rounding out the top ten, though the Aston Martin squad's P1 time was fifth fastest in the combined rankings of both sessions.
Jody Fannin was the fastest man in GT4 for Team WFR (2:00.554). However, their advantage over the nearest class rivals was just 0.407 seconds over APO Sport's James May and Alex Osborne. Zoe Wenham and Dominic Evans, the closest championship rivals to Team WFR, were fifth fastest 2.5 seconds off the class pace.
The Checkered Flag's weekend at the Avon Tyres British GT Championship continues later this afternoon with the live coverage pair of qualifying sessions to set the grid for the two hour long races tomorrow.
