4 channel would be nice. The impala system is a 3 channel setup, with the rear sensor monitoring the pinion speed on the rear diff. Since I'm going to be using both the impy front rotors and the rear end, everything is already setup for the impala's ABS system - no problems with finding a place to mount the rear sensors, or finding rear brake rotors with the correct reluctors. The hardest part of the ABS swap is going to be finding a place to mount the ABS unit. Same goes for the cruise control.
