What is the norm on tracking are wheels set parallel or toe out or to toe in.

It depends on the wheels that are doing the driving. If rear wheel drive then the front wheels should toe in half a degree and if its front wheel drive then the the front wheels should tow out half a degree. You see it depends on the driving wheels. If its rear wheel drive the front wheels (under accelleration)will try to pull out and hence the toe in. If, on the other hand its front wheel drive (on accelleration) the front wheels whill try to pull in hence the front wheels should toe out.;) And at this stage im not going to mention four wheel drive or racing spec.

front wheel drive will do me fine . in imperial measurement how much would half a degree be .I understand it is measured from the centre line of the wheel and it is the difference between the leading edge of the wheel and the trailing edge.measured between the two wheels.

Eric, this info is totally wrong, It is not FWD or RWD related its car specific.

You remarks of FWD or RWD are not true since my V70R toes in,so did my Saab turbo. Racing cars are something else where toe out is designed in.

A degree is a degree, it's neither metric or imperial. And half a degree is 30 seconds.

Was an E300TD, now a Lexus LS400
I thought half a degree was a McDonald's Employee.

Eric is correct.

On rear drive cars the front wheels are pushed apart, and so the manufacturer's measurement has a built in allowance of exta toe-in to compensate.

On front drive cars the front wheels are pulled towards each other, and so the manufacturer's measurement has a built in allowance of extra toe-out to compensate for that. (The resultant measuremment may well be toe-in, which is beside the point. The priciples are however as above).

eric said that FWD cars should toe out, that is the piece that I commented on,
and I am not talking about the behaviour under driving. My Saab 9000 and my V70r have basic static settings the same as my MB, and thats toe in

I was simply ponting out the basics of steering geometry and normal road car , manufaturers priciples. I did point out that specialist cars such as race cars and possibly some of your cars, Malcom, may need different priciple geometry. So lets not compicate the issue in question here, or the recipient will become confused. Thanks:wink:

Your first answer was incorrect,where you say that FWD cars toe out ½ degree

You have confused the guy with the original question by telling him this, its car specific

They do toe out by half a degree? its normal. Oh I see what you mean, Stay with the normal parameters. Car specific is only for specialist steering. Sorry if i confused anyone. but read my post ont the basic steering principles and they still apply today.

Hi Malcolm, one of my best friends comes from Sweden and he works here for volvo and he agrees with me. They still use the basic pricinciples for geometry.
