Yes ackermann is the positioning of the steering rods so that you need no
toe out and when you turn, the inside tire turns more than the outside which
increases as you turn more.  There have been big depates about its use and
efficiency (Carol Smith has a lot of info on it in one of his great books).
Just wanted to tell everyone a GENERAL jist on it so they aren't going "WTF
is that?"

The difference between tire angles is commonly known as "Ackermann" angle.
But that's another thing altogether, toe out (negative toe in) gets you the

The original post had the right camber.
The toe in is reversed (toe-in means that tyres are pointing to the nose
of the car, toe-out means, they're
pointing away from the car).

hehe... Me, Randy Cassidy, Jarno... we're right. The others are merely
confused! :-)

What amazes me is how big this supposedly simple post grew!

And the number of people who are a bit confused about toe-in.
