The final races in the MSV F3 Cup at Snetterton will see a three-way contest to be crowned champion with Tristan Cliffe and Gino Ussi chasing down current leader Chris Dittmann.

Cliffe, from Mulbarton, needs to close down Dittmann's 25.5 point lead in the twin races on his home circuit but his opponent's experience may well trump Cliffe's better circuit knowledge.

Meanwhile, making guest appearances at the Norfolk venue will be Formula Renault 3.5 racers, Antonio Felix da Costa and Kevin Korjus, who are using the event as a warm-up for the prestigious Macau Grand Prix F3 event giving the national racers a real benchmark to judge themselves against.

The Lotus Cup UK series finish their season this weekend at Snetterton, with Rob Boston holding a comfortable advantage over Stuart Plotnex in the Trophy category, while Norwich's Dave Carr has his sights set on sixth place.
