I have the Sport Suspension on an I (not XI). I had same jumpiness as you describe, so it's not just an issue with the XI. I believe the OEM suspension sucks.

The runflats don't help because they are pretty stiff, but it's not the cause of the jumpiness.

Changed my suspension (springs + shocks) and a world of difference, even with the stock runflats.....car rides smoother, absorbs bumps really well and as an added bonus body rolls are reduced significantly in turns.
