Just a question for this crew.... Has anyone changed their clutch assembly out with something other than just the O.E setup? I'm going to be doing mine this spring and just started looking into this. I have seen non-dual mass conversion clutch assemblies out now with light weight cro-moly (14.5lbs)or even lighter aluminum (13-9.5 lbs)flywheels available. I've heard if you go too light you run into poor street performance. I've been told that our dual mass is about 24 lbs! That's a lot of rotating mass that could be conserved for greater efficiency as well as performance and throttle response.

I would think you don't want to go too aggressive with clutch disc engagement properties, as you don't want to shock load the drive-train. Some of the stage 2 kits look about right. The conversion kits have spring hub clutch discs to help with gear rattle.

Also, I'm not sure exactly what kits are compatible with our set up.
Mine is often shown to be not compatible with the 01-03's as mine is a six a 6-speed. But that is OEM stuff too though. What do you think and does anyone have any experiences.
