It stands to reason the number of owners with single disc AND problems would be far higher than the number of owners with twin discs with problems for one simple reason: Theres considerably more single disc owners!

Another factor more difficult to quantify would be the number of owners who specifically went to dual disc because they ARE driving their car harder than the majority of single disc users. In a case of where you are driving the car at or near it's limits your likely to incur more trouble in general than other cars regardless of the clutch you use.

What clutch release mechanism is commonly used with a dual disc setup?

There are more "internal hydraulic clutch release mechanism" failures than external hydraulic clutch release mechanisms. When you DO have a problem with the internal it's a nightmare repair, especially compared to the external type!

I considered a dual disc after burning up my single plate, but went with a single plate anyway. I burned out my single disc being 'stupid'. The basic problem with EITHER clutch is that you CAN burn it out in a single day if you don't use it correctly! My single plate works fine now because I don't abuse it, but I'm not afraid to use it. The manufacturers 'cover your ass' points made concerning dual disc 'abuse' I believe are valid for both style clutches.
