Hi,
the ackermann effect is one of the most interesting and most complicated things (right behind camber changes in the corner during damper action).
To keep it simple:
The inside tire should always be more angled then the outside tire. This is because the inside tire has to turn a much smaller turning diameter around the corner, while the outside tire doesn't need that much steering lock as the diameter of its turning circle is quite bigger.
I hope it's understandable... If not, please ask and I'll try to explain it in a different way.
@BJ: As the new C-Hubs and steering knuckle allow more steering throw the mounting holes on the steering knuckles are further forward to prevent wobbling at maximum steering throw. To keep the ackermann effect the same the holes have to be further forward aswell.
Cheers
Chris
