Keep in mind that the ⅛” of toe change we measured is across the entire suspension stroke. Realistically, once the coilover and sway bar is bolted on, the car will probably use ⅓rd of that stroke when in motion, unless you dirt drop or something. This means that the ⅛” of toe change across the suspension stroke translates to an almost insignificant toe change when the car simply squats or rolls.
As you saw, the toe curve with a factory set tension rod is just horrific. Addressing it makes a huge difference in the way the rear end of the car behaves. Hopefully you can now see that making these basic tension rod adjustments is not black magic. It only took us 3 minutes to make the jig to allow us to measure the toe curve!
