I'm a bit limited in what I can do by the chassis and the location of the existing mounts. I didn't really want to make any drastic changes to the chassis. So I'm just trying to change things to what I reckon might perform better within the existing mountings.

Currently the big rotation of the upright is a result of the track locator rod (if that's what it's called) working in a different arc to the upper and lower unequal length arms. With this type of setup I think it would be pretty difficult to eliminate all of the bump steer.

With the new setup I'm tying the track locator to the lower arm rather than the chassis. I can still adjust the toe OK and I can tune a certain ammount of bump steer in or out depending on the height I place the pivot point on the upright and how it relates to the pivot where the upright attaches to the lower arm. I can also dial in a lot more negative camber than the stock setup if I need it.

I have to say I'm having fun with all of this and the thought process involved.

Cheers
