MG MGB Technical - Toe in

I would like to have the front toe-in set on a 77 MGB. The problem is that in Germany they set the toe-in with an angle. In the Haynes book that I have, they define the toe-in not as an angle, but as a distance between the wheels: 1/16 to 3/32 in. It is not clear where this 1/16 in is being measured from on the wheel.

What I would really like to have is an angle that the wheel has to be set realative to the straight ahead position. Does anyone know this value.

Steven,

That measurement (1/16"-3/32") is the distance difference between the front tires from front to back. In other words, if you measure at the front of the tire from left side to right, and measure left to right on the back side of the tire, the difference will be the toe-in. Obviously the smaller distance should be at the front (toe-in as opposed to toe-out) and the measurements should be taken at the same height at basically the horizontal centerline of the wheels. You can set this yourself, all you need to do is get an assistant to help you measure. Adjust the tie rod ends to achieve this measurement. The amount of toe-in should be equal on both sides. This is an excellent opportunity to center your steering wheel too, if it isn't already. Please post back if I haven't explained myself clearly.

Hi Steve,
Try www.mgb-stuff.org.uk , there's all sorts of info there, or try e-mailing paul Hunt who runs that site and really knows his stuff.

Assuming a diameter of 24.39" 3/32" of toe-in would be 0.1101° of toe-in on each individual wheel. However, I have 3/16" of total toe-in on my car and even then it starts to undo itself at very high speeds. Don't go for any more than 1/4" or it gets unstable again.

Dunno any more than what is in the manual i.e. 1/16 - 3/32. I don't even know if that is both wheels or from one wheel to a centre-line but would assume both wheels. Also don't know whether the angle is for one wheel to a centre-line or between two wheels. My local friendly tyre place has never heard of a toe angle in 20 years, even for German cars, only a distance
