Mine don't clunkI just did a search on the strange 10 ways and I hear the struts clunk a lot (or used to 2+ years ago).
i bought the mm kit for strange struts(other brands were included but don't remember which ones) and already had mm c+c plates installed. I love this setup and have no complaints at all. Maybe mine is just "lucky"? Idk. I believe @HotFox has the same setup and he liked it also(if memory serves) and he probably drove his more(obviously mine hasn't moved much...grrrr
)Edit: I drove it about 5-10 (25-75mile round) trips this year around 500miles I would guess and no issues/noises that I could hear(it is a loud ass Flowmaster kit afterall. Lol)
