The car has more grip in corners, especially the middle part. But: if there already is a lot of traction, long camber links can slow the car down in turns.

A short link makes that the body doesn't roll as far, its tendency to roll drops off as it rolls.
It feels as is the car generates a little less grip.

That pretty much sums it up I think, hope this helps.
