McLaren 'running on the edge'

Suzuka - F1 title contender McLaren has promised to throw everything, "including the kitchen sink", at the final races of the 2010 season to keep Lewis Hamilton and Jenson Button's hopes alive.

Hamilton is 20 points behind Red Bull's Australian Mark Webber with four races, including Sunday's Japanese GP, remaining. Button, the reigning champion, is five points further back.

"We're throwing everything and the kitchen sink at it," managing director Jonathan Neale said at a media conference on Wednesday.

"If we can pull a modification forwards, even if we've only got limited components, I'd rather have the drivers have that fraction of a second in lap time. We're running on the very lean edge of what we've got."

Hamilton failed to finish three of his last four races and McLaren have fallen 24 points behind Red Bull in the Constructors' standings.

Neale said his two drivers would have plenty to test at Suzuka in Friday practice.

"Certainly we're taking everything we took to Singapore, and some more, to Japan," he said.
