I'm still having some noise (used to it by now) and memory steer (slightly annoying) from my KW V1's, especially after I had the top mounts tightened a little more earlier this year. A common solution to this are apparently thrust bearings, that go between the bottom of the spring and the spring perch:
I can't seem to find any suppliers of these in Europe, while they're just $30 or so in the US. I measured the thread on my V1's to be 52mm, but the spring perch is a little wider as it has a lip to keep the spring in place.
I can't measure this lip with the coilovers installed, but would prefer to disassemble them only once. Does anyone know what size thrust bearings I should get for KW V1's? Common sizes seem to be 60mm or 66mm, what sound about right with the inner size being 52mm.
