If you REALLY wanted to do it, you would need to gut the stock valve so it is just a pass through, and then install aftermarket adjustable prop valves in the rear lines. One for each side, because this is a diagonal split system.

Um, do you have your own proving grounds I don't know about? How would you go about doing high speed dynamic testing???? let alone safely . . .

I know what happens in a car when the rears lock up first. I know I don't want that. I also know that Ford really played it safe with the biasing,



If Ford played it as "safe" as you claim, they would have cost reduced out the rear brakes entirely. Ford still has performance targets, both internal, and regulatory to meet. So, rear brakes are biased as much as they safely can be with the factory brake components.

and that while 70-80% of the weight is still on the rear tires under hard braking, only 10% or so of braking force is applied there.



This is damn near the funniest thing I've ever read. A car w/ a 80% rear weight dist. wouldn't be able to steer around a corner, it would understeer like mad even under mild cornering.

I want a better match, so that when I threshold brake under worst-case scenarios, I put just a tiny bit less than makes the rear go first. I know how brakes should be set up for racing, I just wanted to know how to get them there.



Get more aggressive pads then. Better performance all around. Are you going to be actually racing your contour? on a track? Do you have high performance driver training? Do you have brake development training to know how to actually tell where you are when modifying the bias?

Probably not on most if not all of those accounts. I'd recommend sticking with street parts, or at the very least stuff available from reputable brake upgrade suppliers.
