Rear suspension design - squat and toe?

Someone was telling me that as the rear end squats, the rear tires actually toe in due to the multilink rear design. So dialing in a touch more rear toe is unncessary.

True?

If it is that is brilliant if you ask me. That is also nice to know for the track.

Yes, that is correct. We had a camera mounted on the rear to verify this during an autocross.

The toe-in adds stability, otherwise you will have a car that oversteers and hard to control. You will need static toe to have straight line stability too. The only time you will ever want less the OE toe is you have eliminated rubber bushings in the control arms.
