The best FCAB replacement that I have found, that maintains the proper offset, is the Condor bushing.

If you’re wanting better feel in the steering, you can adjust the pressure in the Z4M power steering pump. Lowering the pressure will give more feedback, making the steering feel more solid. Obviously lowering the pressure lowers boost, so more effort is required.
An excellent thread below provides information on our hydraulic steering systems. See post #5 for the DIY on lowering the PS pressure.
