Anyone running the JBR Billet Rear camber arms? Are yours noisy?

Installed these along with coilovers etc. Getting a pretty pronounced "chatter" coming from the rear at very low speed like 5-10mph. I've had two mechanics look at it (one of them twice), and after trying to figure it out for a couple of hours, one of them came to the conclusion that it's the heim joints on those camber arms, and there's really nothing that can be done since there is no bushing in that joint. I tend to trust him as about half of his clients are all SCCA guys that come to him for track prep etc, but I just want to know if any of you running these have a similar chatter.
 
Get a rubber boot to cover the heim joint and pack that thing with grease. You could also give powdered teflon a shot but it probably won't help. If you want to maintain some sanity you can order SPC #67420 and call it a day.
 
Had a GT 500 Mustang with $4000 rear suspension on trade a few years ago. No sag at launch but noisy as fuck. Was all the Heim joints all over. Sold to a track guy.
 
A good heim joint will NOT make noise. Jump to QA1, Aurora, or FK. FK has the best selection of metric/stainless steel/Teflon lined joints, and you can order how tightly the ball fits into the socket. They are a wear item, even the good ones will go bad on a street car in 1-2 years.


4 good rod ends costs about as much as those arms do, so I'd guess those aren't top of the line bearings coming from his shop.
