Default Front toe out: what effect?

I adjusted my front camber this weekend, and so had to adjust the toe as well. After a couple iterations, I ended up with just over 1/8" total toe out. Since I'd heard (mostly here) that a little toe out was a good thing, I decided to leave it that way. My question is: what effect should I look for from this change? I've heard that it helps with turn-in, but how exactly?

Complete alignment and spring settings if it matters:

Front: 1/8" toe out (total, measured at tread), -2.5* camber, 375# springs, stock bar.

Rear: 0" toe out, -1.9* camber, 400# springs, Comptech 22mm bar at full stiff.

This is on a 94 Integra LS.

Thanks!

It will help the car in initial turn-in but it may be a little bit darty, when going in a straight line expecially on road crown or if there are ruts work inthe pavement. 1/8th toe out is about as far as you might want to go unless you are autocrossing and trying things out.

My street CRX has about this number for quite some time. Some people call it darty but I like and am used to it and like the turning response. It will keep you on your toes if the road is very rutted. Locally there is a section of interstate very worn by semis and the car is quite darty there. More toe out can cause speed scrub as well in a straight line.

OK, so it should be more responsive at turn-in. When driving on the street I did notice a slight tendency to want to follow lines in the road, but it doesn't seem particularly darty so far. The steering effort also seems to have gone up slightly, but that could just be the difference between the Azenis (my track tires) it's currently wearing and the BFG it usually wears.

here is a link that might help.

If the car is set up with toe-out, however, the front wheels are aligned so that slight disturbances cause the wheel pair to assume rolling directions that do describe a turn. Any minute steering angle beyond the perfectly centered position will cause the inner wheel to steer in a tighter turn radius than the outer wheel. Thus, the car will always be trying to enter a turn, rather than maintaining a straight line of travel. So it's clear that toe-out encourages the initiation of a turn, while toe-in discourages it.



With toe-in (left) a deflection of the suspension does not cause the wheels to initiate a turn as with toe-out (right).
