If you look at the simplicity of inputs (no pitch, yaw, roll, sensors, traction control, stability control, etc) and the fact that the load in an on-road vehicle can vary by several hundreds of pounds, plus the upgrade-ability of aftermarket caliper/rotor packages for OEM vehicles means that it should function very well in this particular application.
ABS isn't speced by the manufacturer to account for aftermarket brakes. Increasing the weight of a vehicle isn't a problem. Decreasing and increasing the grip (and brakes) is as the ABS computer 'knows' how fast the car can possibly decelerate. If the computer 'thinks' that the wheels have slowed down faster than it thinks is possible (due to more grip, better brakes and lower weight for example) it will let off the brakes and so will *increase* braking distances!
