Copy these new lp files to your c:/ sierra/GPL/tracks/Cadwell folder, replacing the existing files. The new ais are faster and slightly more aggresive - certainly more challenging - but also prone to mistakes - especially at the end of Park Straight... Look out for some lap one grass-tracking on cold tyres around Charlies... These ais are by no means pefect - but their behaviour is fairly typical Cadwell so I hope you will enjoy trying them. Many Thanks to Carsten Meurer for supplying excellent replay laps for conversion - you will be pleased to know that I didn't use the fastest lap he provided!
