When you lower a DC5 without changing the steering arms you have to wind out the tie rods to get the static toe back where it belongs. On the other hand, when you lower a DC5 and change the steering arms at the same time you don't have have to wind out the tie rods to get the static toe back where it belongs, it's pretty much right where it is.
Maybe what you are describing is simply puting the steering arms' length back close to where they were before you lowered it.
Of course, you can't have bump steer in a race car, so the target is always zero. In a production based car we very rarely achieve zero through the whole range of travel suspension, so the compromise is zero within the most commonly used travel. That 50 mm of bump and 25 mm of rebound I talked about in the previous post.
We shouldn't ignore the rear bump steer, it's just as important for handling, you just don't feel it as much through the steering.
