A few questions about bump steer.

At S ride height, can I use the tapered bolt that comes with the Baer kit or will it be too short?

I watched a video demoing the Longacre bump steer gauge and one thing I don't understand is how the gauge reading is not impacted by camber change induced by suspension travel. As the suspension compresses, doesn't negative camber increase and wouldn't this impact the reading?

Thanks.
