Nylatron bushings ?

[280i]

My car has never been as precise feeling as it should be. Previous owner installed some sort of red polyurethane bushings but they seem a bit soft to me. Has anyone installed Nylatron bushings on their car? I am very much chasing that direct feel that I believe should be on my car (car already has alloy steering mounts).
Any thoughts would be appreciated. (car is a 1971 vixen 2500)

or as an alternative I would also entertain some urethane ones that can be obtained in a hard durometer rating.
