You can read more about it here: Braking problem - malfunctioning ABS
RE the braking issue... which I don't think is what you're having, but I'll respond to this

My temp solution is to continue firming up the suspension... don't know if this will work yet... but after talking this through with a nissan test engineer that has 1,000s of hours tracking 370z's, I'm pretty certain the root cause is differential wheel spin rates... ie one wheel picks up off the ground (or just slightly) and spins at a different rate, freaking out the computer and putting it into a safe mode / ice mode braking condition... there might be an RPM cut-off that engages with this ice-mode, haven't confirmed... in any event, a very stiff suspension should minimize the wheel lift... obviously not a solution for everyone... the alternative right now is as chris says go with gentler brakes that are less likely to slow down any given wheel abruptly or perhaps find a different abs computer... no real good solutions just yet
