I recently had mine replaced, along with the flywheel. I was told it has a little greater clamping force than the original (2002). I t does feel like it has a little more bite, but the pedal feel is light compared to my old one.
I don't really know if it's any different. The original unit was pretty heavily worn (30k miles), so that could account for the better bite of the replacement.
Clutch shudder is just as bad.
