I have yet to replace my clutch and DMF but have purchased LUK parts that I got for a good price some time back and kept for future.
I did however do some research before purchasing and was advised by most people not to do the Single Mass conversion due to vibrations and lack of smoothness. Being a BMW I did not want to affect my comfort at all so chose to stick to the DMF.
