The outcome of the Michelin Porsche Club Championship will finally be settled at Donington Park over the weekend of 23/24 October as a double header meeting wraps up the 17-race season.With the best 13 scores to count, double-points jokers and bonus points for starting the final round of the championship, it could take a calculator to finally decide the overall champion, but things are looking good for Richard Lambert.Racing his Carrera 3 in class two, Lambert has led the championship since playing his joker in the very first race of the season at Croft back in April. He has since won the class regularly and finished strongly overall in a fantastic season. If he has two more decent scores this weekend, he should have done enough to win the title.Class one is wide open, however, as just four points split Ian White (3.2 Carrera) and Tamworth charger Peter Morris (968CS). Their year-long battle is set to go all the way to the end of the second race on Sunday and will surely provide a dramatic end to the season. No longer in the championship battle is Chris Egginton after a hefty shunt in qualifying at Spa, but if Egginton is back on the grid at Donington he will be a strong contender.Rob Williams (Carrera 3) and David Botterill (924 Carrera GT) are the other class two front-runners, but Botterill may be absent due to a clashing fixture at his home circuit of Croft. Meanwhile, Fraser Robertson's 944 is looking set to wrap up class three after a superb campaign, with Chris Stewart's 911E leading the chase.
