At the current time we do not have plans of making a rear BMW Performance BBK.

Mathematically speaking, brake bias will not be significantly changed. Yes it will be slightly push to the front but a more aggressive pad in the rear of the pad can easily compensate for this.

Our parts applicator puts the 3.0si in a slightly different location than the other Z4s when adding parts (if that makes any since) long story short I just smacked my parts guy for not clicking the box that links the kit with the 3.0si. It was over looked this it should also fit the 3.0si as like you said the king pins and other front end components are shared.
Guys make sure you're wheels will clear the BBK, some people have noted needing 5mm spacers to clear the calipers.
HERE is a template we have that you can print, cut out, and use on your wheels to see if the rotors and calipers will clear the spokes and barrels.
