I can only speak for the SSL dual rate coil-overs on my Roadster with factory 5 link rear. I still use as supplied settings of pre-load and damping which I recall is about half way on the clicks. When touring with
's humungous suitcase on the back I add a couple of clicks on the damping. They cope fine even with full tank and have never bottomed out. I think the 5 link rear allows more travel than leaf spring versions though
If concerned I would experiment having noted present settings.
