Franchitti soon had the Porsche up into second place and closed in on the Viper as the young Scot drove a brilliant race. By lap 12, Franchitti was able to take the lead by diving inside the Viper into the hairpin. As Franchitti pulled clear, Wilson settled into a safe second with the other Parr Motorsport Porsche of Matt Turner/Ed Horner in third. Less happy with the conditions was Warnock in the Lister, and he slipped down the field as the car struggled in the wet. A first lap spin had already dropped the Michael Caine/Bobby Verdon-Roe TVR Cerbera well down the order.
With 28 laps run, the safety car was back out after the Marcos LM600 of Ken Thomson was left in the hairpin gravel trap after contact with the Porsche of David Jones. Several cars headed to the pits, including Franchitti and the fourth placed TVR Tuscan R of Rob Barff/Martin Short. However, with a long train behind the safety car stretched around the track, both cars were forced to wait in the pit lane longer than they would have wished before being able to rejoin the race.
After a further seven laps of racing, the race was halted early after the Chrysler Viper of Curtis Hayles/Stephen Day was left stranded at the hairpin after a spin.
That drama left Harvey/Wilson ahead by nearly 12 seconds when the result was declared at 43 laps. Franchitti/Burt took GTO spoils and second overall, although it could easily have been a shock overall win. ''This was one we really had to win. The car has been fantastic, wet or dry,'' said Harvey.
Franchitti, meanwhile, was elated to prove his class in a stunning drive. ''It's great to show what I can do,'' said Marino after the drive of the race. The result takes them to within two points of clinching the GTO title.
Jordan managed to haul the Lister up to fourth overall, but knew that he could not challenge Harvey for victory. Points for second in GT were a relief for the Lister squad after a difficult race. Right behind the Lister was the Andy Purvis/David Leslie Marcos LM600 after an excellent race.
Turner/Horner made it a great day for Parr Motorsport by taking second in GTO, while Tim Sugden/Paul Knapfield took their best result of the season in third after Sugden drove a great stint in the rain. Hayles/Day were classified fourth in GTO, while Short/Barff were a dejected fifth, having lost what would have been a top three finish.
