Default dynamic toe change in the rear of EP3 under compression

So as I understand it, the EP3 rear suspension toe's out under compression (i.e., when you get on the gas and transfer weight to the back). All the older civics toe out under rebound (i.e., when you transfer weight off the back). What's the details behind this difference?

From a few folks that I autocross with. Apparently, the newer celicas do the same thing.

The fronts, since we're talking about dynamic alignment changes under compression, will tend to toe out during compression... </TD></TR></TABLE>


Really??? I thought it was the other way around. Front toe-in during compression and rear toe out during compression.

slight tangent: that would be kind of like passive 4ws, right?

It's not the kind of steering change you want, though.

If you're at, say, 135-140 and need to go into threshold braking to slow to, say, 45 to make a turn on a track, your tread patch at the front becomes HUGE at the same time you've gone positive camber and toe-out in the rear.

This can make for a very nerve wracking couple of seconds while the car slows down because you feel that if you even breathe wrong the car's going to go shooting off in another direction.

This is why you'll find yourself wanting to change your suspension alignment theory as you get faster on road courses.
