the braking components that influences the feel to the driver. You like the change in feel, somebody else may not. I think it's a bit much to assume that the way a braking system feels good to you is what somebody else should like as well.
And as for dancing on the fine line of the traction circle, are you implying that a skilled driver would not be able to do that with stock brakes?
I certainly agree there are reasons for getting a BBK. They look cool, and they're more resistant to fade, if you're having problems with fade from your stock brakes. They'll also probably change the way the braking system feels, whether or not that is a good thing is dependent on what the person driving the car thinks about the change.
A BBK for a daily driver that may see one, possibly two track events in a year, is not a no-brainer.
