Dirt Rally 2: "Toe in on the front increases stability at the cost of responsiveness, however too much can cause the vehicle to understeer. Toe out on the front increases turn in, however this can cause vague steering."

Dirt Rally: "A negative toe angle on the front wheels increases stability but can make the steering feel vague. A positive toe angle can increae turn-in response at the cost of stability."
(not relevant because CM does not indicate what they mean by "negative" and "positive")
