I agree 4a completly solves the acceleration skipping in the wet, but around a round a bout at reasonably speed it still slides horizontally. Defibatky the tires with 6000lbs on them I guess. My problem with 4a is the steering feel is absolutely aweful all the time. Heaven forbid trying to park at the grocery with 4a on. I would understand it from 4h, but lots of vehicles have 4a without destroying the steering.
What steering mode do you have it in? Comfort/Sport/Normal?
Wonder if that makes a difference, 4A and Comfort or Normal...4A comfort might be 'best' for you.
