Supercar action promises superb sights and sounds at Snetterton this weekend with the British GT Championship continuing its most successful season ever at the Norfolk venue.

Currently the Porsche 997 GT3R rules the series, but all three of the Trackspeed cars were heavily damaged at the recent Silverstone event allowing the BMW Z4 of Oliver Bryant and Marco Attard to triumph.

While Trackspeed has a race to repair their cars the BMW team will be determine to keep hold of their series lead which may result in a conservative strategy while the Porsche crews, led by the Nick Tandy/David Ashburn pairing, will have to race flat out to close down the 17 point advantage of the BMW Z4.

United Autosports McLaren MP4 12C was first past the chequered flag last year in race one and should again prove rapid with former Grand Prix racer Mark Blundell in the driving seat of their Audi R8 LMS Ultra.

A quartet of Ferrari 458 Italia GT3R's plus the rumbling Mercedes AMG SLS GT3's, who may find the tight infield section of the 300 not to their liking, plus a pair of Aston Martin Vantage GT3's will ensure that whoever wins will surely deserve to celebrate.

In the concurrent GT4 category Redgate/Lifetime Racing, based at Watton, will be looking to continue their strong form shown at Silverstone with Dan Eagling again leading the teams driving duties as well as acting as team manager.

The Norfolk-built Formula 4's make their debut at their home circuit with King's Lynn's Martin Brundle presenting the winners their trophies. Leading the new series is Jake Dalton, who is a two time winner, as is Matt Bell who currently lies third in the series while sandwiching the pair is Charlie Robertson who won the last race

The Ginetta GT5 Challenge always entertains with Will Burns leading from Brad Bailey with the VW Cup, VAG Trophy plus the VW Mk2 Golf series in support with racing from 1.40pm on Saturday and 9.25am on Sunday.
