New national grades for the Formula Two stock cars come into effect for the first time this season and that will have a bearing on a number of Cornish racers at the next race meeting at the United Downs Raceway, St Day.

The action continues at the raceway this Sunday at 2.30pm.

Young Chris Cuming of St Mellion, Jon Kind of RNAS Culdrose, Callington's John Smith and Roger Willcock of Hatt, have each been promoted as a result of good performances in early season.

That should leave the likes of Hewaswater's Andrew Bennett and the Darley Ford pairing of Matthew Deeble and Jason Walters to benefit from front of the grid starting positions.

After a long wait since the opening St Day event, Des Caddy of Lanner will make only his second appearance of the season.

Since the opening fixture in March, Mark Moon of Penwithick and Jeremy Moss of Fowey have each unveiled brand new cars which they aim to race at St Day.

The day's stock car races are sponsored by John Smith Tyres of Callington.

The favourites for honours will be star names such as track champion, Mike James of St Allen, Truro, Tim Farrell of Plymouth who was the feature race winner at the opening meeting, and former world champions Bill Batten of Newton Abbot and Dave Luscombe of Totnes.

Amongst the entry of bangers are Chris Gillbard of Launceston and Shaun Kitt of Liskeard, who featured in a huge head-on crash at the last meeting.

Jeremy Harvey of Pendeen is due to make his debut.

"Nippy" Neil Martin of St Austell was the stock rod final winner at the last St Day meeting, but Rick Lee of Tregrehan has made a winning start with a feature race success at Taunton.

At that same fixture, Brad Brannigan of Redruth raced for the first time in 2003, whilst Richard Bradley of Twelveheads returned for the first time since New Year's Day.

When the youngsters in the Ministox were last at St day, 12-year-old Callington star, Ashley Rundle executed a home straight rollover, but has since bounced back to move to the top of the Westcountry points chart.
