Actually it was no joke at all. Weight over the rears will most likely allow the rears to do more work and the car 'hunker down' a bit more as it won't nose dive. You might be surprised. Granted, it's not altering fluid pressure which seems to be your desire.
There is static bias and there is dynamic bias as well. You are chasing static. Try some stiff springs in the front or stiff shocks in the rear- these things will change dynamic bias as well.
Sure, you can gut the stock MC and valve bodies and run full line pressure out back. Better plan on the prop valve or two. And you'll be adjusting it when you have friends in the back seat too- it's that weight thing again.Or if it's raining, snowing, etc.
Want to really take a stab at this then lets fit prop valves in the front. That should prove interesting. You'll of course need two of them- one for each channel. Or would you prefer to Tee them? You can do that too if you like. Forget tha ABS working correctly however.
Other thoughts; source some larger bore calipers for the rear. Not sure what might fit. Buy a larger rear rotor kit (yea, I sell them) or some super sticky rear pads. All will effect static and dynamic bias.
Find some smaller front rotors. Smaller front calipers. Put in junk pads up front. All of this will do the same as the front prop valve in reducing front effectiveness.
Nobody has suggested driving backwards yet...lol (not that one's a joke)
