[Synchro909]

I set the toe in by putting a piece of masking tape with a vertical line (fine ball point pen) on the front of the tyre tread of one wheel. The gauge and tape are at axle height. Then the pointer on one side of the gauge in place on the line, I put another on the tread of the other wheel. Now, I roll the car forward till the tape is again at axle height and check the distance between the lines with the gauge. If it is off, I repeat till I get a difference of about 2 - 3 mm front to back. I never measure anything. Perfect.
