i installed mh kw v3 for two weeks. the rear springs keep making knocking noise. at first, it is on the right, then on the left as well. but after a week, the right makes almost no noise but the left continues. some paint starts to chip off from the spring end at the top, where kw perch is in direct contact with the spring with no rubber in between. the handling is great but the knocking noise is really annoying. i search many discussion forum and i think this is called spring bind, in which the coil of spring hit each other. my shop sad the only solution is to wrap the coil with plastic.
i play around with the compression and rebound setting and it seems kw recommended is the best. i dont track so i think i should have bought the cheaper kw v1. of course, i didnt know aftet trying myself
