Tom Wrigley denied Michelin Ginetta GT4 Supercup championship leader Tom Oliphant a fifth consecutive pole position by the narrowest of margins to card his maiden series pole at Silverstone.
Rob Boston Racing’s Wrigley edged out Oliphant by four thousandths of a second with a best effort of 58.233s, a lap time one tenth of a second faster than last season’s pole time.
Oliphant got the all-important edge on his title rivals though, with HHC Motorsport duo Jamie Orton and Carl Breeze third and fourth respectively, Orton having been only 0.081s off pole.
Jordan Stilp kicked off his debut Supercup weekend in impressive style with the fifth fastest time, a quarter of a second off pole, ahead of regular front-runners Will Burns and Ollie Jackson.
Returning to the scene of a pole position and double win last season, David Pittard could only muster the eighth fastest effort ahead of fellow series returnees Stefan Hodgetts, Callum Pointon and Carl Boardley.
Graham Johnson led the way in the AM class in twelfth overall, the newly-crowned British GT4 vice-champion over half a second faster than his nearest class rivals Colin White and Connaire Finn.
