I like that some of you 8 series owners have that stock front bumper skirt w/ big air dam inside, however I still cant' figure out whether I gotta change the whole front end bumper to have that lower skirt or it's just an add on piece that could be added to 840 stock bumper...It almost looks like it only comes from a factory BMW but I couldn't find the part number from a dealer. Im confused! If it's not a factory option, who sells it then?

Are you looking for something like these? most are just add on to existing bumper.

IMHO, the CSI and the Zeemax are the 2 better quality of them all. ACS is just too expensive.

Thanks, thats what I was looking for, is the CSI version. I like it the most as well. Where would be the best place to purchase one and is this the add on lower piece?

Hi

The CSI is a complete replacement lower cover. It is not an add on.

There is also a rear cover/underspoiler that goes with it.

This is a Dealer item. Try www.buybmw.com parts department. Dave or Al

They discount rather deeply on 8 series parts and can also deliver a set painted to your body color code with matching Euro CSI mirrors if you desire.

Here is the

And I highly recommend getting the Rear Diffuser (http://www.realoem.com/bmw/showparts.do?model=EG93&mospid=47334&btnr=51_2091&hg=51&fg=15) to ensure proper airflow.
