430 F1 Clutch

Hi, I own SportsMaserati over in the UK and I need some help regarding the F1 or CambioCorsa clutch that has been the thorn in the side of the 4200/GranSport owners over here in the UK and I am sure globally too.

Our issue is that our Valeo clutch, that can only be purchased from Maserati or ES turns out to be the same as the F430 system....or more so it can be fitted and works.

Now, its a little more expensive, ok, but our issue is, when they go in the F430, what is the norm?

Does the clutch start purely slipping when its worn down or do you get the same problems as we do in our Maseratis, were the clutch cover spring fingers, or tangs, collapse, rendering the car undrivable?

Appreciate your feedback.
