The country's most popular sports car championships are the theme for the Castle Combe Circuit's two day Summer Sports Car Spectacular on Saturday and Sunday July 4 & 5.

TVR's, Porsches, Ferraris, Caterhams, Ginettas and LM 3000 Protosports provide the backbone of the entertainment, each of these championships traditionally providing superb racing at the Wiltshire circuit and drawing crowds in excess of five figures.

The TVR Tuscans have been favorites at the circuit for many years, their combination of rather more power than roadholding providing wild entertainment and attracting hordes of TVR owners who worship one of the last great British sportscars.

Similarly up-market action is on show from the Pirelli Porsche Cup, with the most delicious examples of the German Marque in action. From 911 Carreras to 993s, 928s and 968s divided between three classes, the competition is so hot that any one of ten drivers is in with a chance of victory. Local fortunes are in the hands of Mike Salmon from Shalbourne (Wiltshire) in a 993.

The Goodyear Maranello Ferrari Challenge race is notable for its huge entry of 30 cars including three from Pewsey namely, Graham & Mike Reeder in an F355 & 380 GT4 respectively and Nuno De Brito E Cunha in a 365 GT4. Bristol sends Shaun Powell in an F355B.

As for the two Caterham races, superlatives are likely to be inadequate to describe the intensity and unpredictability from these diminutive machines. This year sees a change of specification to Superlight R 1.8 litre and Roadsport 1.6 divisions, both Rover powered and just as hectic!.

The LM3000 Championship is likely to be the fastest race of the weekend and features the return of Bath's John Barnard with a fresh 320 bhp engine installed in his car. Barnard will also be a contender for the Mobile Windscreens Special GT Championship race in which many of the other LM3000's are also entered.

Finishing off the sports car theme is the Bridgestone Ginetta Championship including Bristol's Clive Steeper.

Single seater fans have plenty to be happy about too. The incredible Formula 600 Championship returns, Formula Renault has Jason and Jeremy Timms upholding Gloucestershire honours and the HEAT Formula Ford 1600 Championship continues with High Elliot from Bradford on Avon still heading Class B in his Van Diemen. At the front of Class A is Robin Parsons from Salisbury in his Swift SC92F.

Finally, saloon car followers can indulge in the Proton Coupe Cup for the second time this year and round five of the Pagid Performance Braking Saloon Car Championships. Amongst the many local entries, Radstock's Julian Howell is at the top of the points chart in his Class C Mini, whilst Bridgewater's Tony Dolley is looking largely uncatchable in Class B in his Vauxhall Corsa.

There's also the BRSCC Tomcat Vento Challenge, with Rover 220 Turbos versus VW Vento VR6's.

Saturday's action starts at 8.30 am with qualifying, racing getting under way from 14.15. Sunday practice is from 9.00 am with racing from 12.00 Noon. Admission charges are £4 Saturday/£10 Sunday for adults and £1 Saturday/£2.50 Sunday for children, OAP's and paddock transfer.
