  1. The front toe needs a datum point and that point comes from the rear, and it's called the thrust angle.

    Most tyre shops if asked what are you aligning to would say each other... No you're not, the front wheels are aligned to the middle of the rear.

    I am instructor in geometry  and suspension calibration and i was asked by the biggest fast fit company in the UK to train their area managers.

    Not knowing their level of understanding, i initially start at the basics. Nearly all of them didn't know about the thrust angle!. In the end i decided to drop the training because most cannot understand geometry for more than two hours.

     

  2. The toe plosions if not even to both wheels would definitely off-set the steering position.

    What reads strange is the datum point for the front toe is the middle of the rear? Basically the front wheels don't know where forward is. So if the rear toe is correct

    it will use that as a datum point.

    Has the steering wheel been moved to its original position? Reason i ask it the car has a steering position sensor meaning it reads the position and takes charge in the event you lose control.
