Hey guys here is one our new 335i customers having his CDV removed for those of you who don't know what that is, bmw's have a clutch delay valve so they clutch engagement will be "smoother" but in hindsight for a person who drives spiritedly it causes a slower enguagement and also wears your clutch more. the process is simple between your slave cylinder and clutch line there is a check valve, remove the valve and re-install the line and your done! Enjoy the pics! Thanks...
