Steve I did the same upgrade about a year ago fantastic results. M's and others are no problem in the corners! Most tracks in America are bumpy so using a stiffer sway bar can make the Z3 rear suspension jumpy when hiting a bump in the corner. Springs and shocks are the way to go if the cost is not objectional. In replace of a larger sway bar you can install stiffer bushings for even more direct steering and handling. In my case I had a more radical alignment away from factory specs to give me the handling I wanted. This was done by a pro race team so I don't have the detail except that they had to add some parts.
For the track under advice of the pros I keep all shocks at their softest setting.
I know alot of you will dissagree with my comments on sway bars. Please read Carrol Smiths series of books, Prepare to Win, Engineer to Win, Drive to Win, ... Also I have seen one Z3 with stiff sway bars was throwen into a wall by a bump at a turn.
