The size chart on the site made picking the right clips for my naked roof painless, and they snapped onto the towers with zero wobble. Two in the set meant I had a spare, though honestly the first pair felt solid enough that I doubt I'll need it.

Wasn't sure which size I needed for my naked roof, but the fit chart on the site made it easy and these clips locked the towers down solid. Zero wobble on the highway at 70.

Snapped right onto my towers and the fit on my naked roof is dead solid — no wobble at highway speed. Having the exact size options made dialing in the fit way easier than I expected.
