Is there a way to adjust the brake bias on a 2gen GT - I know it has a proportioning valve but think it´s sealed from factory. Shop says my setup is acting as though its 90-10 f/r and I´d like to push it back to 80/20, or even 75/25 with the right pads. I go through front pads before the rears even look worn.

whazup man, "sealed from the factory"? things are only sealed if the epa has guide-lines set, ie: MAF, or VAF.
factory combo-valves ar not adjustable.
how does the shop know what the bias actually is?!
dude if the brakes arnt working right you should stick to the basics, like condition of the rotors, calipers, and pad quality.
have you had the brakes bled before? if so maybe you jammed the valve stuck. :-?

One of the biggest things that will make the brakes seems like they are not biased properly is improper adjustment of the rear discs. that darn little torx screw under the bolt is the key to great braking with your gt. read the shop manual for how to adjust it then play from there and find out what works.

I recently did a 4way brake job on the car and found that the right rear caliper had been dragging. Changed pads, rebuilt calipers, new hardware, seals etc. So I have already covered the basics.

Adjusted the torx screws to eliminate drag - it´s a very fine line between just touching the rotor and being ineffective.

Maybe I don´t need to adjust the brake proportioning valve. Perhaps it´s already out of adjustment and a new one/rebuild will get it back in spec.

Stock perportioning valves don´t go out of adjustment because they aren´t adjustable to begin with. They are a block of metal with a few holes drilled into it. The only way it will go out of whack is if a piece of debris gets stuck in one of the holes. Then you would likely not have any braking on that circuit at all. If you are so determined it is the perportioning valve yank it out and blow some air through it. While you are at it replace ALLLLL of the fluid in you Master Cylinder and flush your line. Don´t forget to bleed as well because air will cause a hydraulic circuit to malfunction as well. Ad Adjust all of your pads to spec, not to feel, unles that is what the book says to do.
