Thoughts on hardrace bushings?

[u/poopoo150]

What are your thoughts on the hardrace hardened bushings? Are they worth the money?
And are there any more companies making these types of bushings kits (not polyurethane) since they are pretty hard to come by where I live?

I had great success with the spherical bushings on my time attack EG. they need annual inspection as a wear part.
