The Radical Sportcar Challenge crown will be decided at Snetterton this weekend with Thetford's Jack Lang hoping he can use home track advantage to gain the upper hand over title rival Oliver Barker.
Lang will be hoping for better fortune than in late August when the series last visited the Norfolk track and he endured a difficult meeting which saw him loose his advantage to Barker while a miserable final race at the recent Brands Hatch round undid his race one victory.
For the local racer it's win or bust this weekend making for a thrilling climax to the season.
Brockdish's Bonamy Grimes, along with co-driver Johnny Mowlem, will be looking to build upon their first overall British GT Cup victory at the recent Donington Park round with their brand new Ferrari 488 Challenge car.
