Whoa!!! some people have WAAAAAY too much time on their hands
Firstly where on earth did McLaren get the Ferrari data from?
Secondly, 'braking power' as you put it, per tyre is equal to the
coefficient of friction for the tyre * vertical load on the tyre. As the
coefficient (typically a max. of 1.4) drops only very slowly with increasing
vertical load, the ability of the tyres to decelerate the car is near enough
directly proportional to the vertical loading, which will be a combination
of car weight (there will be weight transfer from rear to front) and
aerodynamic downforce, which depends upon speed and wing settings (all of
which will be changed all weekend). So where is all this taken into account?
The 'braking force' figures you quote are constants, which make no sense.

I'll not waste bandwidth/time on the rest of this. Fortunately the guys at
Ferrari and McLaren *do* know what they are doing :-)

Sure they are ....

Good 'bikes, but they don't go round corners too well ;-)

I guess, if Schumacher gives an interview in English and makes a minor
mistake, you'll doubt his apillidy (ooops!) to drive his car?

Oh, and Schumacher's mechanics were pushing his Ferrari around
the track to gain him 290km/h topspeed???
Dream on... I want to see the 2 sec in Silverstone and Hockenheim.
So in Your opinion Mika Hakkinen is the worst driver in F1? He
will be glad to know that.
I have read countless similiar calculations over the years. If
they are not backed by evidence on the track, they are
worthless. And Your calculation is backed by no evidence
whatsoever.

Shame his understanding of vehicle dynamics doesn't match up to his English

c>I have read countless similiar calculations over the years.
Fascinating. A more relevant, and considerably less sophisticated
'calculation' would be to time how long it takes each team to change
a set of tyres and refuel. I also wonder why they don't just
cut the driving part out of F1 altogether. It would be a lot
cheaper, and no less exciting.
Thanks for ruining my summer holidays...I thought I left all this
behind two months ago :).
Seriously though, where did you get this info?
Mike
