Just got it back from alignment; it's much better. Camber, caster, & toe-in were all off a bit; though nothing major. It will still do it, but only if I am almost (3/4+) towards full lock to begin with. Guess that's as good as it's going to get.

 

squeal?.
if a tire is 12 in. wide and you turn a ? 30 foot circle the outside of the tire goes about 6 feet longer than the inside. figure it out. almost 10 %
if pi was 3.0 the figures would be 90 and 96!! hence the squeal.

 

Thought I'd chime in on the subject.
My 2006 h3 a 74k miles and no tweaks done to torsion bars, it returns to zero no matter how sharp my turning angle is. Fast turn, slow turn, it always travels back to center.
