I know in working with grand am team engineers they were pretty convinced the issue is related to rears having far too much bias. They left area before I had a chance to go to smaller 350z Brembo rear caliper.

Have you kept notes on how much fuel you have and rear tire condition when you experience ice mode? I can tell you my car locks up rears more often even with 5 gallons less than full. Also suspension settings have had influence - lack of bump in dampers in front allow too much weight transfer allowing rear lockup too.

Our cars are nose heavy. Shift weight off light rears quickly and what do have? ...ice. Add poorly programmed abs ice mode and you have constant ice mode issue when you try aggressive late braking.

But it might be air in ABS system? all of us having same issue? Would like to hear more on this theory.
