I have one sitting on my shelf in my room. I used it for a while but the whine of the engine annoyed the shit out of me. I will tell you this though, it eliminated 100% of my wheel-hop. I could dump the clutch from any rpm and not feel a bit of chatter. The adjustment bolts did come loose one time though and the car started to make a pop noise when taking off. All I did was go home and tighten all the bolts to it. I yanked off the TQ arm and replaced it with the stocker with ES Inserts, but, anytime I go out to the track, I swap MM. Definetly not a street worthy MM but it lets me utilize all my traction at the tracks.
