The install instructions from their page mentions 2 washers, I looked on the inner side and the circlip does not have a washer between it and the bushing inner steel tube. I'll email nolathane now that I've found it.

I only noticed the noise after fitting the hardrace rear camber arms, but they're all done nice and tight so I'm confident that the noise isn't coming from them, can't see any other signs of contact around the suspension and have removed the rear anti roll bar to troubleshoot.

I greased all the rear bushings at the same time as fitting the camber arms, so I think the RTA bushes are more free to move laterally than before greasing causing the knocking.
ah ok, i thought they were pedders cos had same replacement installed when i purchased a car and they said was pedders.
ive had knocking sound after installing spc rear camber arms too in EG. noise is gone after went back to stock camber arms.
i was sure all bolts were tight too.
