Hi Drew,
I replaced the ones on my car a little while back, they were a few years old and just not up to the task anymore. Tried to find replacements but was told they didn't make them anymore. I have gone back to standard ones as I was told that solid mount ones would be too harsh. There's been some discussion on this in some recent posts. They do help with a bit more camber. Are they new? If not make sure the bearings are in good nick.
