I think the main difference with the E9X is that you don't have to do nearly as much to get the car close to neutral.
I ran a 32mm front sway and no rear sway on my s2000 without aero - it handled beautifully. I added the front way to neutralize the oversteer the s2000 has after going to a non-staggered set up, then it still was still a touch loose in the rear, so I removed the rear sway all together.
With the proper camber up front on and M3 that a track setup would have - the rear would oversteer more due to more grip than before (all other things equal).
