keep in mind, this is what I felt in my opinion, some peoples opinions will change, so keep that in mind.
Less Anti-squat (less washers on front of pivot)/More Pro-squat (more washers on rear of pivot)-More forward bite, less side bite, a small amount of traction loss turn-in/middle of corner.
More Anti-squat (more washers on front of pivot)-more side bite, slight traction increase on-power, a bit less forward bite. Too much Anti will make the rear very loose and figity.
Anti/Pro squat only affects when accelarating or braking, not while "coasting" so don't expect it to give more steering or traction if you are just coasting through a turn. Once again, this is my opinion, not necessarily right, but what I felt.
