we learned to be better drivers?        rob

I don't make bias changes very often because I never push the car that hard 
and deep. On my old Radical you were playing with bias every few laps as the 
tires went away--if you didn't you'd be entering turns backwards.

It's not that hard to know you need a change. Whatever turn requires the 
most braking is the one you want to adjust for. As you brake for the turn 
you should feel the back end get light and "skippy" without any feeling that 
it's going to step out. If you get all your braking done in a straight line 
it's not so critical, if you're still braking some when you're turning in 
then you need to get it right to go fast.

If you don't feel the back end get light then you don't have enough front 
bias. If the back end starts to step out and you have to modulate the brakes 
to stop it, then you have too much on the front. That's about it.

Usually these kind of turns are fiddly things, and there's not a great deal 
of time to be made up by doing them better, but proper brake bias adjustment 
is important for the big high speed turns so you can get the braking done, 
get back on the gas and push the nose into the turn. You won't feel the bias 
problem there, but if your car has unbalanced braking you won't be able to 
get through the turn anywhere near as fast. Ultimately mid corner speed is 
where all the lap time improvements come from, and the only way to get there 
is balanced braking and getting the car settled. =
