Things I hear keep leading me to this conclusion... which makes me not want them.
I have no problem with simple mods (like the H6 rears) that enable the rears to generate more brake torque, thereby allowing me to also create more front torque while maintaining a balanced system with greater stopping power. Too bad the front/rear Wilwood systems for the WRX suck. I do know I will not be upgrading my brakes further until I find something that will increase braking power, not just fade resistance.
