Does the Z have a rear toe-steer problem?

It is a big part of the reason the 350 was unpredictable on corner exit.

the principle is the same. the rear toes-out as the suspension compresses. that's why the wiggling butt. the 370Z is much improved vs the G35C, but as i mentioned, the design shares the same principle.

except the shortened torque arm creates toe-in on compression. the funky wandering feeling described here (and in many other threads) comes from excessive toe-in.

I can't speak for the G35 for sure, but when I did bump steer measurements on my 370, I started at ~1/16*, and went to ~3/32* at full compression on the rear.

You can hook your Z up to a bump steer gauge if you don't believe me.

Would an adjustable torque arm allow you to tune out some of that toe change?
