it will become difficult to match rolling radius but as you have a haldex system it shouldn't make too much of a difference.

it has been linked to transmission wind up in torsen equipped cars where the diff can't deal with the rears travelling less distance than the fronts.
negligible in most situation otherwise a wheelspin or lock up would do the same
