this is the email I sent to racingbrake and their response (basically they agree and say to use different pads front and rear with their setup):
RESPONSE:
The thread only shows the calculation on different set up and assume both
front and rear pad have the same coefficient of friction. While if you go to
track usually you would use more aggressive pads for front than rear, so our
kit would end up to be pretty close to stock bias.
Try the current set up yourself. If you have HPS (come with our kit) front
which has higher Mu than stock rear so the over all bias would be same as
stock. Or if you upgrade to HP+ for your front you may have to upgrade rear
pads to HPS as well.
Nothing to worry or concern, RB offers you complete satisfaction. Once you
test in the track I believe you will better understand there is a difference
between theoretical discussion and practical application.
By the way the torque unit s/b ft-lb, not lb/in.

I would like to draw your attention to a thread at http://www.legacygt.com
regarding bbk kits for our cars. The thread indicates that the bbk kit you
sell for the legacy gt, and which I have on my car, may not be a good match
to the stock rear brakes. I would very much like to hear a response from you
about this as it concerns me - particularly for the next time I take my car
to the track. Thank you.
