Radialbearings.
The V1 60 mm Radial Adapter from Destination Sideways: a radial bearing that fits between a coilover spring and its lower perch so the spring can rotate relative to the perch.
Online ordering is not open yet. A limited number of V1 sets from the original run are on hand; email to ask about one.

What the bearing does
The perch turns. The spring should not.
This schematic shows a strut with a fixed upper spring seat. The lower perch turns with the wheel, while compression asks the coil to rotate. Friction at the seats can wind up the spring until it releases. With the adapter under the spring, the perch turns on a bearing instead. Motion is exaggerated to show the mechanism.

Where the bearing sits.
The adapter sits at the bottom of the spring, between the spring and the coilover’s adjustable lower perch, so the spring turns on a bearing instead of on the perch. The tech page has V1 photos, drawings and the figures from the original product page.
