John,
I think I see the misunderstanding in the rear steer discussion.
If I have read your posts right, your front and rear axles are still parallel and the center lines of the axles are offset from the centerline of the chassis. I know my Woods car does not have what we would call a rear steer option.
In what oval racers call rear steer, the rear axle is not parallel to the front with the left side wheelbase being slightly shorter than the right.
What you are using we just call offset. We use it, both right and left, all the time.
I think simple terminology differences are causing the confusion.
