IMO, spherical bearings(the real name of "pillow balls") in the upper plate are overkill on cars without struts (like a mkiv) since the shock doesn't locate the suspension, and affect suspension geometry if it moves around a little. They tend to loosen up over time and make noise, so I'd avoid them. My car spends a lot of time on a racetrack, and I don't have them. My Intrax came with a plate, but it uses rubber rather than a spherical bearing.Originally posted by Grant:
<STRONG>What about pillow mounts? What are they? Do they make noise? I certainly don't want to add anything that will start making some racket as I go over bumps. My lightweight flywheel is bad enough.
Thanks for any help,
