mdane,
I will qualify this with the fact this is like asking how long brake pads last. The most significant factor is the driver/driving conditions. Brakes can last 10K miles or 60K miles, same car, same brakes, different driver/driving conditions.
With that said I think 30K-50K miles is the typical NSX clutch life. Some get 10K - some get 70-100K, but I think they are the exception.
There was a discussion on the big list recently and one person pointed out he was getting an average of 15K/per clutch, another person chimed in an explained that due to the angle of his driveway, he was always slipping it on the way out, EVERY DAY, and he also got around 15K!! ( And this was on two cars, not only his NSX) So, you can see how driving conditions also play a huge role. Until this post recently, I was mostly focused on the "driver" as opposed to the "driving conditions".
I have a 1991 with 31K and my clutch is original and feels fine, but... it could slip tomorrow. ( I have a steep driveway
)
I drive is a spirited manner, and try to keep my foot OFF the clutch pedal as much as possible. I NEVER "milk" the clutch. If my foot is coming up it's always coming ALL the way off. I was given that advise when I first learned to drive manual, and it has worked for me.
HTH,
