Can the control arms on this be used with ANY coilover kit? It seems that most of them require their own manufacturer kits. Also regarding the K member. Can it be used with any motor mounts for the same reason?
Any brand coilover will work with this kit. As for motor mounts, in some cases depending on manufacturer, there can be a embossing on the face of the mount that sometimes needs to be ground off. Aside from that, this kit will accept any of the 4.6 style mounts.
