Pretty damn cool, always wondered how they’re put together!

Now that was very interesting viewing, not your everyday car clutch.

2 things don't make sense to me in the video though.

At the 2:30 mark, he just slides the titanium stand bolt sleeves over the standbolts as if the sleeves are not internally threaded - yet we've seen the sleeves are threaded and seconds later he adjusts their height proving threads are engaged by turning them!? (Perhaps slick video editing out of the turning of all the sleeves during assembly?!)

Then at 4:30 he presses the release fingers by hand to move the pressure plate. Now either that guy is super strong (Steve Austin, The bionic man strong), or the clutch was assembled without springs or pro-stock cars have feather weight clutch pedals... which one?
