Thanks for the info. Out of interest where does it come from as the TV footage showed point 8 was a 5.0g stop repeatedly when on board with Hamilton.

It's on Brembo (brake manufacturers) website. http://www.brembo.com/ENG/Formula1/2008/ Thanks to bar555 for making it more convenient for us though.

2009 DATA



Situated in Valencia's recently-revamped marina area, the track is 5.473 kilometres in length and boasts top speeds of over 300 km/h - the cars will reach 300 km/h or more five times per lap, and calculated an average speed per lap of 225 km/h which will be the eighth fastest of all Grand Prix tracks.
Three times per lap the drivers also have to brake to about 80 km/h which will be as demanding for the brakes as the Montreal circuit. The longest full throttle section will be along the harbour where the drivers will drive at full throttle for 13 seconds. The front straight is 185 metres long and the shortest of all Formula One circuits this year
The layout of the innovative track is challenging too, with 25 turns (11 left and 14 right) to test the drivers to the maximum
