Hi there, I need to set the tracking on the rear wheels. One source says
Quote:
As a starting point, set them at 1/16” toe-in.

I'm just checking I'm using the right measurement points...I would assume I measure the overall width from one tyre to the other. The width of the outer edge of the front-most part of the tyres and compare to the overall width of the outer edge of the rear-most part of the tyres. And make sure the front overall width is 1/16" narrower than the rear measurement.

Is that right?

not sure about the details but make sure you measure from the same point on the tyre i.e. you need to turn both wheels half a turn in case wheels or tyres are not perfect.

I setup a string line box around the car to measure the rear toe in.

Thanks guys. Whether I use a string line or just measure it, is the theory right that I posted?

Is the measurement for example 1/16" narrower over all or say 1/16" in from the string line? There's a few ways that measurement could be applied.

You need to get the toe in as close to 1/32” (0.8mm) each rear wheel.

I also tried the rear wheels straight and found it ok but I went to toe out it felt very skittish.

I take the measurements against the sidewall at the same height as the manual says to do the front wheels but on the outside.
http://www.ausmini.com/manuals/Mini%20W ... eering.pdf

"Measurements must be made on a 14.5" diameter (368.3mm) on the sidewall of the tyre at a distance of 9.4" (239mm) above the ground."

Here is a photo showing my very technical setup. I use a brick at each corner and 2 pipes that I roll up to put tension on the string. If you zoom in you will see 2 chalk marks on the sidewall. They are 9.4" off the ground and 14.5" diameter. All you need now is a ruler or a vernier calliper depth gauge to measure the distance from the string to the sidewall.
