I took it out and reconnected the line. 97% of all clutch cars out there don't have these things and they seem okay right?

Anyway I highly recommend it, but don't expect it to make a night and day difference.
First comment - exactly my thoughts after having an S54 with and one without the CDV.

Second, yeah, a lot of cars with way more clutch burning power that ours probably don't have a CDV. Does anybody know if Mustangs, Vettes, Camaros - all the Big 3 high power cars have them? It certainly can't be about cost because it's an extremely cheap, basic part. I don't get the argument that they put it in there to "protect" the drive train and suspension unless BMW is pretentious enough to think their customers buying manual trans cars can't drive them. Few other manufacturers seem to believe that a CDV is necessary to protect the drive train....

But I digress, and I thread jack - I will stop now....
