If you have more grip on the back due to the beem, then you will get more understeer than before if you were getting it before...
Changing the rear beem surely can't affect how the front wheels behave on the road....unless i am totally misunderstanding it.
I can't explain it from a angles perspective, I'm afraid you'll have to go on my version of the arse dyno
.
Before the beam i only had the adjustable tcas and these made a very good improvement on the turn in, but when i went into a corner especially a roundabout, the front would turn in nicely but the rear would not know what to do, and(maybe through a shift in weight at the rear) the rear would lift and want to carry on straigh and the car would then start to "drift" wide.
Now with the beam(and admittedly coilovers plus corner weighting) it stays a lot flatter and the rear "tucks in more" and follows the front.
Hard to explain but maybe the above will make some sense
