James Walpole holds a slender two-point advantage in the chase for the Class A title in the MG Peter Best Insurance Challenge which completes its 12-round series at Snetterton this weekend.

The King's Lynn racer will probably need to defeat James Darby in both races to ensure he claims the title although dropped scores and extra points for fastest laps and pole positions make the mathematics highly complicated, ensuring a nerve-racking finale.

Thetford's Simon Hutchinson will be hoping to upset the regular racers in Class C as the local driver aims for victory with his mighty Midget against the bigger V8 powered MGBs.

A fantastic battle is in prospect in the Morgan Motor Challenge with local favourite Keith Ahlers aiming to defeat Russell Paterson, who won at the circuit earlier in the season, while Mathew Wurr has also proved rapid around the Norfolk track in the past.

The Thoroughbred Sports Car series always provides a heady mixture of 60s sports cars with a trio of March-based racers, Bob Lines and Colin Jones in their MGAs taking on the newer MGB of Kevin Swann in Class B.

The race for outright honours will see Roger Connell's TVR Griffith taking on Great Yarmouth-born Tony Lee's Morgan +8 while a raft of MGB V8's and Jaguar D Types will also be in the mix.

Tony Howe has been a long time supporter of the MG Metro Championship and will again be a leading runner, as will Dick Trevett and Andrew Ashton.

A Four Hour Relay race ends the weekend on Sunday with 27 teams contesting the events. Norwich's Tony Le May is team manager and lead racer in the Mini Miglia's team along with circuit specialist Peter Baldwin, who has won in excess of 300 Mini racers.

Racing starts at 12.15pm on Saturday and resumes at 9.25am on Sunday.
