hello I drive e91 325i and I have been driving control arms with poly bushings a while (Strongflex).

Now my question is if I should run the original new wishbones bushings or replace it with another set of polys.

I ask because I've seen new kits that include original bushings of wishbones and everything else poly bushings.

I kind of got used to the sound of control arms. Relatively high NVH.

Superpro offer kit with original wishbones

Which control arm bushing?

The rule of thumb is you don't want poly in a bushing that has motion in more than one axis. Twisting in any direction other than the axis of the bushing causes binding, which is unwanted spring loading and can fatigue metal. Those should be rubber, or ball joints.

Control arms (furthest in front).

ok, I try re-lube poly as much as I can before I afford mono balls.
