Included Angle

The Included Angle is a diagnostic angle that's obtained by:

• Adding positive camber to SAI
• Subtracting negative camber from SAI

 Toe-In and Toe-Out 
When a pair of wheels is set so their leading edges are pointed slightly towards each other, this is referred to as toe-in. If the leading edges point away from each other, then it’s toe-out.

• Toe settings affect three major areas of performance: tyre wear, straight-line stability and corner entry handling characteristics
• For minimum tyre wear and power loss, the wheels on a given axle of a car should point directly ahead when it is travelling in a straight line
• Excessive toe-in or toe-out causes the tyres to scrub, since they are always turned relative to the direction of travel
• Too much toe-in causes accelerated wear at the outside edges of the tyres, while too much toe-out causes wear on the inside edges
