Nissan 350Z clutch worn out - any similar experiences?

[944Tman]

One of my friends has been through 3 clutches in 10,000 miles, and has commissioned an engineer who found that the clutch was permanently loaded, hence casuing premature wear.
He's a car nut, the car is pristine, never tracked. Nissan say its down to driver abuse, we differ.

Does anyone else have any similar experiences ?

Please feel free to PM me if you want to keep this off record.
