BMR rear anti roll bar makes noise.

Do a google search for ----> threaded clamping collars - should be able to find something and probably save a bunch of cash over something marketed directly as a "high-performance part" .... just pick something made out of good quality material that can handle the load.
Kind of interesting that mine is less than a year old and it didn't come with this update.
Now..where can i get a set of those anti walk clamps? Fantastic idea!!!

These are also called "Split Collars" and you can purchase them from most any bearing supply house. Just need to select the split collar that will fit the bar properly when torqued down.
I installed one on mine as I felt my rear end a little loose going around some high speed corners and was concerned the HR Bar could shift slightly. After the split collar got installed, my issues were solved.
