Conceptually it's pretty simple to retrofit, but finding a car with a very similar weight balance seems trickier. In talking to him (Jochen), he said the tire diameter is irrelevant as well as the actual weights on the corners. So long as the tires are the same height, and the balance is close, you're golden.

You just touched on a good point . If your car is running bigs and littles for wheels , then any ABS system will be a nightmare . The system looks at wheel speed diferential and then compensates by reducing pressures to the wheel it thinks is locking up . The differential in wheel speeds with different tires would confuse the system into thinking the rear tires are braking quicker than the fronts (the bigger tires will be turning slower , if I remembering it correctly) . This in turn would give you uneven braking .
