So i recently purchased this s2000 with 63k on it but recently noticed a strange high pitched whine in the rear. Almost like a laser gun charging up kind of sound, along with my clutch buzz which i dont particularly like i hear a small buzz when in engaging. The transmission feels fine and grips well though. The noises freak me out, so i made a video to be more exact and so some of you could chime in. let me know.
