Not sure TBH- but I know it's a completely different clutch from the mz3 to the ms3, I've owned both, and the clutch in the ms3 is FAR more aggressive than the mz3 clutch, for obvious reasons. Might have been a change when they went to the 6sp manual from the 5sp, which is what the earlier manual mz3's had. I'm not sure when they went to the 6sp across the range.
