This weekend will see the climactic weekend of this year’s Porsche GT3 Cup Challenge GB as the final two rounds take place at Silverstone as part of the BTCC support package.

Run alongside the Carrera Cup GB and managed by Porsche Cars, the series has been given the honour of stepping up to join the Carrera Cup on the roster of BTCC support categories. Add to this fact that the overall title will be decided on Sunday, it promises to be a fitting and exciting finale to what has already been a tense season.

The championship leader heading into the final two rounds is GT MarquesJames Birch, who has enjoyed a stunning season which ahs seen him take five wins and only finish off of the podium once in ten races. He heads to Silverstone with a twenty-two point lead in the standings and two more podiums – a likely prospect – would be enough for him to claim the title. The Buckinghamshire racer said: “I’m really looking forward to the weekend and hopefully wrapping up the championship. I just need to finish and beat Steve [Liquorish].

His main rival is Steven Liqourish of Team Parker Racing, who has enjoyed an equally fruitful season that means he is the only man who can come between Birch and championship glory. With six podiums to his name this season, he cannot be counted out of contention, as he illustrates: “Anything can happen in the last two races. It’s going to be very tight on the National Circuit.

However, Liquorish’s Team Parker team-mate Justin Sherwood is the man with a run of form at the moment, with three wins from the last four races to his name. Others who also stand a chance of the podium or even the win are John Ferguson and local boy Peter Smallwood.

Fourth in the title race is remarkable rookie Mark Cowne who partners Smallwood at Parr Motorsport.

The grid will see two new faces as young Harry Whale (son of all-rounder Harry) takes up a seat at IN2Racing and the experienced Nick Staveley returns from his five-year sabbatical with sibsport performance.
