Default Rear toe-in what is the effect?

I know most nitro buggies come with 3 deg. of rear toe-in out of the box. But what is the effect of using less toe-in for cornering? I run on short, hightly technical tracks where straight line stability on long straights is not an issue. Does rear toe-in effect push coming out of a turn?

Toe is the angle (inwards or outwards) that the tires point when the wheel is straight ahead. Toe-in means the front of the tires point inward, and toe-out means they point outward. Zero toe means the tires are parallel to each other. The biggest effect toe has on the handling of the car is on stability. When a car hits a bump or enters a corner, forces on the tires act to steer the car off to one side, making the car unstable and difficult to control. Toe-in counteracts this, improving stability. Toe-in also causes understeer during initial corner entry. Interestingly, toe on the rear wheels has the same effect on handling as toe on the front. Toe on the rear wheels is useful for tuning the handling of the car as it is exiting corners.

Front Toe "IN"
Slower steering response
More straight-line stability
Too much will casuse greater wear at the outboard edges of the tires

Front Zero Toe
Medium steering response
Minimum power loss
Minimum tire wear

Front Toe "OUT"
Quicker steering response
Less straight-line stability
Too much will cause greater wear at the inboard edges of the tires

Less Rear Toe "IN"
Less straight-line stability
Less traction out of the corner
More steering
Higher top speed

Intermediate Rear Toe "IN"
Intermediate straight-line stability
Intermediate traction out of the corner
Intermediate steering
Intermediate top speed

More Rear Toe "IN"
More straight-line stability
More traction out of the corner
Less steering
Less top speed
