And while this can be annoying, I only found it so in the beginning. Once I got used to it, I didn't think twice about it. I've driven manual cars for over 20 years and I personally think that the CDV is a nice precaution to have. I believe it will prolong the life of the flywheel even amongst experienced drivers. A properly functioning valve should be undetectable under normal driving and only showing up when you get abusive with the clutch. When I give my best to shift smoothly and properly, I can't even tell that a CDV is there. It's my understanding that CDV allows the dual mass flywheel a soft engagement to prevent the flywheel from bottoming out and damaging the ears that press against the springs.
As a manual driver of 20+ years, the removal of the CDV from both my E36 and E46 (both of which were driven over 150K miles on their original clutches) was immediately noticeable and an instant improvement.

I can accomodate the restrictor in the clutch line by slowing my leg movement so the fluid isn't trying to move too fast but why would I want to do that?
