that bit about it being a downgrade is just silly... why would you do such a massive upgrade (single to 4 piston) and not use a brake bias valve???
a mate of mine had 6piston AP's installed on his supra which made the rears lock up first too... until that is, he installed a brake bias adjuster valve.
larger caliper needs more fluid to travel the same as a smaller caliper, so obviously, with an upgrade, you'd adjust the bias more towards the larger caliper till you get it even.

silly?
your mate "upgraded" to 6 pots, that made the rears lock up first...
so now the rear brakes are more effective than the front and lock up first? what part of downgrade doesn't work here? 
the point is that even tho a '4 pot' or '6 pot' caliper is used, that may result in less force being applied to the brake pads by the new calipers, so thus more force needs to be applied to brake pedal to get same braking force (for same disk size), and if the rears lock up first due to the fronts now doing less, you install a brake bias valve to make the rear brakes less effective??
so, we've made front less effective due to caliper "upgrade" and we've 'dumbed down' the rear brakes because the front "upgrade" meant they were too effective..
ie, reduce front braking force, and thus need to reduce rear braking force...
and this is not a down grade how??
maybe i'm confused, but if you decrease the braking force, i don't see how that is a straight "upgrade" (of course pad area, heat capacity of the disk etc is also a factor)
