Basically it is a different clutch assembly (in a way). Later minis aka Rovers were all vetro. You can change clutch set-ups but it involves changing everything including the flywheel. Also the slave cylinders and throw arms are different but that is irrelevant, the clutch will work fine no matter what slave set up you use. |

ALL Australian made Minis & Mokes were pre-Verto. Thank God... they are an abomination, IMO. 
The pre-Verto clutch wasn't broke, so Rover `fixed it'. 
[edit] a Verto clutch is made arse-about compared to a normal Mini one. The flywheel isn't attached to the crank, the diaphragm/pressure plate is. The pressure plate design is similar to that in a `normal' car, however they can be a b!tch to get off the crank. Only benefit of Verto (IMO)- lower pedal pressure. Disadvantages: 1. More complicated. 2. MUCH heavier clutch/flywheel assembly. |

So, let's see.. the flywheel's primary purpose is to dampen the power strokes and smooth power delivery from the crank, but when the clutch is disengaged it's not doing it's job? |

I, personally, like the verto clutch from a driveability sense. A nicely weighted flywheel which makes the engine respond like an engine should, not a rev-happy Toyota tin-box, with no real power. Clutch is also a much nicer, more driveable feel.

It depends what you now call the flywheel.. look at a Verto diagram and you'll see what I mean.

The flywheel is still attached to the crank, its just bolted onto the back of the clutch pressure plate first. Friction plate and primary gear are the only bits spinning independently. |
