There are pros and cons to a diaphragm clutch living in the Pyrenees Ian.
It normally involves machining the flywheel to get clearance and a lighter flywheel means that the revs drop away faster between gear changes with a 3 speed gearbox……
Clutch may be ‘lighter’ but there may be a trade off just so you are aware. Citroen fitted that big lump of a flywheel for a reason.
