Both BMW Sauber drivers were left cursing their luck after a strong performance at today's Japanese Grand Prix ended in the team only picking up three points.

Heidfeld, who had been challenging for a podium in the early stages of the race, found himself drop from fourth to sixth after problems during his final pit stop and bad fortunate during the safety car period.

"I'm very disappointed," he said. "Fourth place was within reach but several things went wrong today, especially at the second pit stop when the rear right wheel nut got stuck. I don't want to complain. These things can happen and normally we have very good pit stops. That was when I lost a position to Kimi, and I rejoined the race just behind him. When the safety car came out I lost another position to Nico, who was lucky to refuel while the safety car was out."

His team mate Robert Kubica was also dealt a bad hand when his mid-race battle with world championship leader Jenson Button was brought to an abrupt end because of traffic.

"The entire weekend was unlucky for me," the Pole said. "Yesterday I wasn't able to show my good pace due to the red and yellow flags. Today I was stuck in traffic a couple of times. I lost a lot of time at the beginning of the race with a heavy and understeering car. Once the car was lighter and I got into my rhythm I was quite quick. I was then very unlucky with my first pit stop, as after the stop both Kimi and Nick were in front of me."

BMW Motorsport Director Mario Theissen was happy with the performance of the outgoing team but not the outcome of the race.

"That was a strong performance from us with a disappointing end," he said. "Nick was quick and well on his way on fourth. Then he lost a position during his second pit stop due to a sticking wheel nut. He lost another position during the safety-car-period when Rosberg passed him after his pit stop. Coming in ninth, Robert missed the points by just a small margin."
