I just replaced my original clutch at 183k miles because the throwout bearing failed. The clutch wasn't even done yet. So, a CDV may cause more wear but it's nothing significant. I just installed a new clutch with a lightweight flywheel. With that said, my friend has the exact same set up with the CDV removed...it's sooo much better. The clutch just feels like it grabs better. I need to get mine out ASAP. And then in my future 135i
