RMS adjustable struts - noise, harshness?

No rubber bushing in the RMS kit = harsher.

Whether you can live with it is a personal deal. Comparable to - I want a streetable engine. What's streetable to one is a crazy race engine to another.

I do know the kit transfer road noise, much like urethane does. If you can live with urethane bushings, the RMS kit is not a big jump, IMO.
