Qualifying honours for the British GT Championship at Rockingham were shared between Mosler and Porsche teams, while one of their title rivals suffered a major set back ahead of tomorrow's two races.

Gregor Fisken took pole for the first of tomorrow's (Sunday) race for the Rollcentre Racing run Mosler, his lap of 1:22.102 winning the battle for pole over his fellow Scot David Ashburn, taking the wheel in the Trackspeed Porsche.

Third on the grid of tomorrow's first race was taken by Juan Garriz in the Argentine Chad Racing Ferrari, the year-old spec 430 pacing the fleet of newer Scuderia models, with the championship leading MTECH car in fourth ahead of one of Essex based Chad's own Scuderia machines – driven by Chris Hyman and Dan Brown.

The second 15 minute session saw the teams swap drivers to set the field for the second race, with significantly faster times on offer.

Another Scot emerged on top – this time Glynn Geddie for Trackspeed – topped the sheets with a time of 1:20.561, just pipping Griffin in the MTECH effort (1:20.579) with Predator CCTV lining up in third thanks to Adam Wilcox. The Ford GT of RPM Motorsport will complete the second row, Alex Mortimer sharing the car with Philip Walker.

In the G4 class Piranha Motorsport took both poles with Chris Bialan and Simon Mason fastest in both sessions with their Lotus 2-Eleven. The Christian Dick/Jamie Stanley Speedworks Ginetta was second fastest in the first qualifying session and fourth in the second session, which saw the debutant Chad Racing KTM X-Bow take the kudos of second place – Michael Mallock responsible for the car in the session. The car's owner, Greek Athanasios Ladas recorded the third fastest time in the first tranche of qualifying.

But while Rockingham will welcome one new car to the grid a stalwart will be missing.

The defending champions – Godfrey and David Jones will not be lining up. Their Preci-Spark prepared Ascari KZR1 suffering engine problems in the free practice session, sidelining them for the weekend and almost ending their aspirations of defending their title.
