Adjusting the toe-in

If you want to do this yourself, try the following: Strap strings along the sides of the car, close to the front wheels. Measure from the string to the edge of the rim. The average of the distance C and D minus N (N is the wheelbase front wheels minus the wheelbase rear wheels divided by two) shall be equal to the average of A and B. A shall be slightly larger than B (½ – 3 mm). The difference between A and B must be identical on both sides. (Measured to the edges of the tires A should be 1 – 4 mm larger than B.)

The CX must be at normal height with the engine running, the tires must have proper air pressure, and the car must have rolled forward before testing. If you need to adjust, the front wheels must be on a slippery surface (f.ex. two metal plates with grease between them under each wheel).

• To attach the strings: you can f.ex. use two long poles that you attach to the bumpers.

• C should be equal to or slightly greater than D (0 – 3 mm). If this is not so you need to have a look at the bearings on the suspension arm.
