Auto Motor und Sport and Giorgio Piola mutually said that McLaren using a structure that controls the flow of heat from the brakes into the difficult-to-manage Pirelli tyres.
The reports said: – Pirelli compounds are the major factor in this season. How many times have we heard the drivers complain already that they did not get the rubber into the work area, which is this year a few degrees higher and has shrunk considerably. Would not it be great if you could adjust the temperature in the tires during the race?
These thought, one at McLaren also employed. And the engineers come up with a creative solution the reports said team’s mechanics regulate the rear braking system in the pits with a screwdriver, the screw being located near the driver cockpit opening.
Gio Piola’s drawings illustrate, the unlimited adjustment affects the rear braking system and the flow of braking heat to the tyres.
But it has not been all good news for McLaren, whose Jenson Button is suffering arguably the grimmest period in his entire F1 career at present.
It might have something to do with the FIA’s recent crack down on the MP4-27’s floor.
Reportedly after the Chinese grand prix, the governing body ruled that the British team had stepped over the line with its interpretation of the rules regarding flexibility.
Scratches had been found underneath the extremes of the front wings, to which McLaren argued that the floor bending was within the allowed tolerances.
“The tolerance is there to account for manufacturing defects,” Charlie Whiting is quoted as saying, after ruling that McLaren’s system deliberately exploited those tolerances.
Auto Motor und Sport said: “The seemingly minor change had major implications for McLaren.”
Mainly Button. The team’s following technical changes, including the higher nose and the modified rear suspension geometry, seemingly worked for Hamilton, but not for the struggling 2009 world champion.
Getting the 2012 car to work for Button again is now a high priority for McLaren.
“The problem is very complex,” technical director Paddy Lowe said. “Our car is good; it just has to be set up perfectly.”
And at the heart of all the F1 teams’ quests for performance at the moment is the mysterious Pirelli tyre.
“I’d say we understand 30 per cent,” admitted Lowe.
