Building the front and rear suspension geometrically more alike is an easier way not to make balance-handling misstakes. If not knowing exactley what we are doing.

So you put the RC as close to the ground as you can so you only have to concentrate on elastic weight transfer? That's a little different. On our cars we have no control over the rear roll centre (watts link) but still, I think if it's possible, it is a very good tuning tool given the way it loads the tyres differently. Not always good, but not always bad either.
The Ortiz article in the back of RCE deals with roll axis inclination this month. Interesting read.
