I appreciate the Stoptech article Gary pointed us to, but unless I am mistaken, Stoptech only makes a front upgrade for WRXs. This would appear to me to at least be a partial contridiction to their article. Assuming the factory setup is fairly balanced, if not slightly front biased, just throwing significantly bigger fronts at it like their product would cause exactly the issues they reffer to.

It appears only the Perrin and Wilwoods have a front/rear upgrade. To what level these are matched, I do not know. Heck, even with the CDM/JDM WRX 4 pots it would be interesting to see if the part number for the stock bias control is the same as the U.S.

This balance is part of the reason my Stealth does not have bigger rotors up front, only thicker, and better cooled than stock. I won't get into the piston and pad area changes, but based on the research I did at the time, combined with more aggresive pads in the stock rears, I ended up with a fairly well balanced and much more consistant system.
