I'm running 4-pot Wilwoods w/Hawk HPS, with the Nabco 97 Nissan U13 Non-ABS MC, Max/Alty U13 rears with OEM pads, basic rotors, and I barely (and I mean by the skin of my butt) avoid too much rear bias.
The brakes work great (also forgot to add Greg's Gspec lines, great stuff), but I will add a F/R Proportioning Valve eventually. Guessing the Wilwoods with 11" rotors bite more than the NX2000 brakes they replaced.
At track speeds and temps, this goes away as the fronts warm up and the rears tend to fade. When they're cold, like AutoX runs, there is rear-bias which can be useful for late braking and initiating some tail-out on sharper corners.
At least on the B13 the PV function is built into the MC, you have to add another PV to control F/R bias.
