Stopping distances are hurt, as is ability to properly trail brake and load.
Remember, stopping distances are determined by tire grip, not by "how powerful" your brakes are or "how much torque/friction you have". By altering the bias, you increase the rate at which the two tires are overwhelmed, and decreas the rate at which the other two are overwhelmed.

With upgraded brakes and tires (especially the tires) wouldn't you expect increased load transfer to the front (assuming straight line braking) and as such you would actually WANT to change the bias to the front as there's more grip available there and now less in the rear?
I'm just bench racing with this idea though since I'm using the stock wheels for winter driving, and Canadian winters (salt) I won't be doing any bbk upgrades anyway.
