I have done a lot of work improving the handling. I have not seen the need to use poly bushings in other than the subframe. Suspensions are designed so that it all works together to result in particular handling characteristics. I stayed with parts that were designed to work together. Primary reason was that the X5 understeers more than I like already. I didn't want to risk increasing understeer. I don't think the increased cost of poly bushings pass the value equation.
Same, on both sentiments. Whenever I buy a new (used) BMW I do the entire suspension. It costs more up front, but saves loads of headaches and time. I have never been a fan of poly bushings on anything short of a race prepared vehicle.
