AS darkness fell on this southern coastal city last night, mechanics for two top teams fielding McLaren F1 GTRs in Sunday's Shell Endurance GT Zhuhai International three-hour race faced the prospect of little sleep. While the West Competition and Mach One San Miguel McLarens arrived safely, the same could not be said for over two tonnes of mechanical equipment. The flight from Britain to Hong Kong carrying the equipment made an unscheduled stop in Dubai, leaving it stranded. Team manager for both West and Mach One San Miguel, David Price, said the equipment was originally supposed to arrive on Tuesday. 'It's certainly left us with a last-minute rush. I was definitely getting worried,' Price said last night. The first one-hour untimed practice session for the blue riband event, which is also the final round of the Global GT Endurance Series, is scheduled for 9.30 am with a second scheduled for 2.30 pm today. Price said his mechanics also faced a second problem: 'There is only one light in the pit area to work under - we didn't bring generators or arc lights with us.' The team were trying to enlist the help of the organisers to get the extra lighting last night. And it wasn't just the competitors who experienced problems with missing equipment. Timekeeper David Bettinson was without graphic display equipment for the television monitors which also went missing in the Middle East en route to Hong Kong from Britain. Fortunately, it appeared yesterday afternoon and will be installed before the first official timed qualifying sessions tomorrow. A capacity field of 31 cars are expected on the grid for the endurance race which will bring the curtain down on street circuit racing here after three years. Next year a purpose-built, Formula One-standard track on the outskirts of the city will be completed. A media inspection of the circuit will take place this afternoon which has attracted widespread interest from both within China and overseas. A total of 250 mainland China journalists have travelled here while another 100 from Hong Kong and 60 international press will watch the seven-event programme on Sunday. The media and racing fans alike should not be disappointed. The very best GT endurance drivers and cars in the world are here to compete in the event. Jon Nielsen and Thomas Bscher in the West Competition McLaren have already clinched the championship but still opted to compete in the final round. Andy Wallace and Olivier Grouillard in the Mach One San Miguel McLaren can cement third place overall, after a late start to the series, with a win on Sunday. A significant driver switch for Sunday's race is Bob Wollek who has raced successfully this season for the Labre Competition Team in a Porsche GT2 Evo. He was also part of this year's Labre Competition team that won in Zhuhai. This time he will drive with Ray Bellm in a Gulf Racing McLaren. Five McLarens out of a total of eight that have raced competitively this season will be in Zhuhai. Challenging them for top honours will be a Ferrari F40 GTE entered by Pilot Aldix Racing and two Marlboro-Mobil Toyota Team Toms Toyota Supra GTs. Included among the driving personnel for Toyota are the winners of this year's Le Mans 24-hour race, J. J. Lehto and Yannick Dalmas, who ironically drove a McLaren to victory. The three-hour international endurance race begins at 12.30 pm.
