Scorpion, on my limited knowledge of bump steer....
In order to have zero, or close to it, the steering arms from the rack need to pivot at exactly the same point as the control arms do. If the rack is wider than the control arms pivot point, you have the steering arms and control arms moving in unequal arcs which can create unwanted bump steer.
Other things such as rack height and outer tie rod end height all plays a part in it also.

I've put a KE70 rack into my Celica. The Celica control arm pivot points are 590mm apart. The KE70 corolla has the control arms 620mm apart. Another idea I suppose would be to move the control arm pivot points on the Celica apart 30mm. But I think this would be a engineering headache, whereas shortening the rack shouldn't be such a headache.

Cheers
Joel
