It was a trick question
I just wanted to understand why Artwork believed it did.
Changing the link length without changing the link angle relative to the arms has no effect on static RC, it only changes what the RC does as the car rolls. Short links cause the RC to rise as the car rolls, so will roll initially and then stop giving a more reactive feeling, long links cause the RC to stay low as the car rolls, so will roll more mid corner (at that end).
So back to the original question, I would lengthen the front link to make the front end roll more mid corner, and I would not lengthen the rear links unless you want a more stuck rear end.
A 3k rear diff is pretty heavy so I would look for on power steering elsewhere, less front droop is a good place to start and a harder rear sway bar also works well on the xray, less rear toe is good if you need steering in high speed sweepers.
