[urq] Alignment Toe Specs

[Brandon Rogers]

This post has got me thinking some more...(watch out!)

So... lets' say static toe adjustment for front and rear is 0, perfectly
straight.  Now if a wheel is not driven, I would expect the drag to "pull"
the wheel somewhat backward under movement, creating toe out?  But with a
quattro, where every wheel is driven, are the wheels "pulled" back or does
the traction "push" them forward, creating toe-in under movement????

Also, Ado mentions checking location of subframe.  How can you tell if it's
off to one side?  I thought it pretty much had one location determined by
the four subframe bushings.

All input appreciated...

On all Urq cars (tire size 225/50x15), I use:
Front = 1° camber, 0° toe
Rear = 30" camber, 0° toe, with no sign of unequal wear, and very responsive
steering.
For the steering response less affected by the road camber changes I use:
Same camber front and rear, but toe in is varied between 5" and 15", as per
liking; same value front and back. Naturally
that the tire size and wall stiffens affect the the transfer of road surface
condition, that is why the toe-in is
preferred. Toe out would make the car very nervous and require continuous
steering input, especially if the rear toe is
unequal and rear initial tracking not parallel with the front. Position of
suspension sub frame could also play the
part, and should checked and adjusted accordingly.
