As you did say in a later post, bigger brakes are primarily to dissipate heat, not to improve brake torque. I would be interested if you had taken temperature measurements during track days and also compared wear rates.

I had the same pad compound for the oem calipers and the Brembo's. I don't have any hard data or temperatures to show but i did experience fade with the oem calipers and didn't have it with the Brembo's (Same pad compound).
That being said I don't remember the temperature of the day for the runs but the sti rotors are heavier and larger so they must have a better thermal capacitance. I also like the feel of an opposed piston caliper vs a floating.
Changing the pads on the Brembo's are 1000 times easier and there is a wider range of compounds made for that pad size. There is also a pretty wide rage of aftermarket rotors for the STI so that opens some options up as well.
You will destroy rotors and with a 2 piece rotor you can replace the ring for relatively cheap. (Coleman)
Are the sti brembos the best brakes out there.. NO.. they are heavy compared to others. but for the price its a very good choice. JUST DON"T DO THE REAR.
on an aside..
be careful using different pad compounds for front and rear. each pad compound will have a different coefficient of friction as temperature raises. Cold you could have a rear bias.. as temperatures raises that bias could change to the front.. and then it could change back to the rear as you get them really hot..
you can also glaze the rear brakes first on a front biased car. There is more to it than just bias.
