If in doubt just delete the CDV. I kept CDV as my car is still under warranty.
In fact, I really don't have much issue with the way 1M clutch operates (maybe because I did not experience the other way) but I could always use shorter clutch travel with that BSM clutch pedal stop unit. How easy is it to install, any downsides?
