That's a fair point.  It's as if 'low' anti-lock braking is enabled at all
times.  I'm not aware of real F1 cars having any form of 'intelligent'
brakes.

First, the brake pressure in the setups is arbitrarily low, and you
can't adjust it from the standard F1 2001 menus.  If you get Turner's
setup tool from http://members.rogers.com/nwalkz or the advanced options
menu from http://www.rsdg.net/ you can raise the brake pressure quite a
bit, and they do seem to lock a bit earlier if you do that.

Secondly F1 2001 attributes a substantial amount of downforce to the
diffuser, so even if you knock both wings off you are still being glued
to the road pretty hard.  The diffuser's downforce is height sensitive,
however even raising the car to the max ride height is not sufficient to
remove all the downforce.  At the base ride height of the Williams, for
example, the diffuser alone has a lift coefficient of -0.932.  I'm not
sure what the frontal area of an F1 car is, but making some rough
estimates the diffuser alone should be capable of around 100 lbs of
downforce at 50 mph, more if you have it running at the nose down
attitude typical of most setups.

I will admit however, after doing some rough calculations, that it seems
like if you knock the front wing off you ought to be able to lock the
fronts at any speed.  The diffuser force is primarily on the rear
wheels, meaning you still should not be able to lock the rears at any
significant speed, only the fronts.

The only other explanation I have for this is brake heat.  F1 2001 does
appear to model brake heat, and defaults the brake ducts to a relatively
high setting.  You can change the brake duct setting with the tools
mentioned above.  Brakes have an optimum operating temperature, so maybe
with good brake ducts you might not be able to get them hot enough at
high speeds.  Just a guess, really.

One thing I just tried to test what I just said was to run the Williams
with maximum brake pressure and minimum brake duct settings.  I should
have messed with the wings too, but I didn't.  Anyway I was able to get
front wheel lock up at 120 kph, which I think is about 75 mph.  So
basically I think F1 2001's physics model is working right, but there
are some parameters that you should be able to adjust that you can't,
unless you get one of the setup tools listed above; and the downforce is
more effective than you might expect.

 Since when should it be this
   I spent tons of time getting my f1 CS 2001 brakes to NOT lockup, then I
see threads here that complain cuz they CAN'T lockup the brakes.  I'm
thinking this was an EA feature fix due to customer input.(just a guess
about that tho..)

I seem to be able to lock the brakes at 200kph+ speeds in the GT mod.
I guess the F1 brake performance could only be commmented on by
someone 'in the know'
