Wheel Alignment (1998-1999): Toe-in: Notes
With toe-in the front part of the wheel points inwards. Toe-in can either be measured as an angle or as a difference between measurement a and b. See following illustration.
Correct toe-in gives the correct feeling from the road through the steering wheel and assists directional stability.
The toe-in angles are adjusted by the tie-rod length.
NOTE:
Toe-in should always be adjusted in relation to the car's driving geometric axis (thrust line) which is derived from the rear wheel toe-in. See Checking Toe-In .
