Isn't the stock TII brake system fairly good to begin with? You have to be pushing quite a bit of power in order to outperform the stock brakes. Wouldn't you benefit from a good wheel/tire/pad combo for better braking BEFORE you go with new brake system?
Chris (OP) doesn't seem to want to talk about his needs much but I'm interested to see everyone's input regarding the best way to improve braking without frivolous expenses.
At what point should the braking system be upgraded? I am under the impression that "if you can't lock up your tires under hard braking then you're outdriving your brakes" but I don't know how realistic/correct this is though.
