Toe in is an often configurable setting of a cars wheel alignment. The front steering wheels can be set to point away (toe-out), toward (toe-in) or parallel (zero toe) to each other. Production vehicles will typically have some toe-in, as it encourages the vehicle to drive in a straight line and provides straight-line stability; race cars will typically have zero toe or toe-out, as it encourages quicker steering response while sacrificing straight-line stability. Both toe-in and toe-out will increase rolling resistance, as the tires will "scrub" even when driving in a straight line. Therefore, the most efficient configuration is zero toe, when the steering wheels are parallel to each other; however this will sacrifice the straight-line stability of the vehicle.
Instructions for mod
Consult your workshop manual for specific directions
Most cars will have a steering arrangement as shown in the picture to the side. The steering rack tie rod ends screw into a bracket at the back of both wheels that steer. Rotating the tie end will increase or decrease the overall distance between the 2 ends of the steering rack. As the steering bracket on each wheel is set a distance behind the centre of the wheels increasing or decreasing the overall steering rack distance will set the toe in of the wheels.
