Do the E93 front sway bar with your tires, it's only $200 and a very nice small mod. Not sure about the convertible models but I'd assume everything swaps. The sway bar and non run-flats is the only thing I've done to my baby - if you have the staggered wheels (7inch fronts and 7.5 rears) you can run 225/45s on the front and 235/45s on the rear, I went star specs for autocrossing but I think it helped my handling a lot. Even with just the stock sport suspension it feels a lot more planted - less floaty and better turn in with less body roll.
