I don't think the clutch position has anything to do with rev. Matching. Or at least not alone. It doesn't do it if you up shift(I don't think). Only if you go to put it into a lower gear. Something is monitored at the trans. I think.
Really, I am not fluid with metric units.
But that is what I thought I remembered from when I bought them.(which was a while ago). They are definitely not 2" so I must have transposed the numbers in my head. I would have to change that to 25 mm. Then. Thanks for the heads up.
