However, the quickest of the Escort Mk1s will be flying along and it is the cars of defending BHRC champions David Stokes/Guy Weaver and Ernie Graham/Robin Kellard that should be the best of the pack.
Stokes/Weaver have had a tough start to the season with two non-finishes after mechanical dramas, so they will be determined to score a strong result on the Severn Valley to get their season on song.
However, category 2 is not just about classes C4 and C5. The 2-litre C3 category is already delivering some mighty contests this season, and it was Ken Forster and John Stanger-Leathes who took their Escort Mk1 to a fine win on the Pirelli. But on the opening event, the Robin Hood, Welsh crew Tim Jones/Don James scored a fine win and will be eager to repeat that victory on home ground.
Other major challengers include the Escorts of Neal James/Kevin Jones, James Young/David Young and Robin Shuttleworth/Mark Midgley.
The Class C2 pace should be set by Vince Bristow/Tim Sayer (Escort Mk1), but youngsters Adam Morgan and Chris Kenyon are getting quicker and quicker as they build their experience.
Category 3
With the Porsche 911RS of Jimmy McRae absent after its accident on the Pirelli, category 3 is all about a gaggle of very quick Mk2 Escorts, all of them capable of challenging for victory. Robin Hood winners Richard Hill and Patrick Cooper and Pirelli winners Darren Moon and John McNichol will be right at the head of the battle, although Moon has never seen this part of Wales before.
Other established contenders include Dick Slaughter/Geoff Dearing, Simon Tysoe/Rob Dyson, Phil and Mick Squires, Charlie Taylor/Steve Bielby, Jason Lepley/Howard Pridmore, Frank Cunningham/Ryland James and Chris White/Chris Dewsnap, while Welsh legend – and pensioner – Terry Brown, partnered by the slightly younger Den Golding, will use his knowledge of these stages to good effect.
