Toyota confident suspension issues solved

Jarno Trulli suffered two identical failures after hitting the kerbs at Turn 8 on Friday, and there had been fears that the team could be forced to withdraw if the cause of the problem could not be found.

But following detailed examination of the incidents in Montreal and at the team's Cologne factory, Toyota believe that the problems were caused by the set-up they were using, so they revised their settings as a precaution.

Toyota's technical chief Pascal Vasselon believed the changes, allied to advice for the drivers to avoid the kerb at Turn 8, should ensure no further failures.

"There is no way we can monitor the suspension in the race, but the technical counter-measure should be enough in itself to put us in a safe window," he said.

"We want to be 100 per cent certain, not 99 per cent. And we know that accepting a slight performance penalty we can be 100 per cent certain.

"We are convinced that the technical counter-measures are enough - but we are being extra certain. And we are ready to accept a slight performance penalty."

Vasselon was hopeful that the set-up changes and the more cautious approach for the drivers would not hurt the team's competitiveness too much though.

"It's difficult to say - what we are confident is that it won't be major problem," he said. "We will go to more camber - we don't really need it - and a slightly softer suspension. It should not be a night and day difference."
