Default Getting Access under Engine with BW Splitter Installed

sooo. Went to go do valve adjustment on our new track car. It still has the factory fan shroud and mech fan. Need to get access under the car to get the fan shroud off.

Also has the Bimmerworld CF front splitter. The BW splitter design is one piece splitter/lip that wraps up around the front of the bumper and it attaches with plastic rivets.

So it Seems like if we have to get under the car the whole bumper needs to come off. Can anyone else with the BW splitter give some advice on removal?

Of course the difficulty is compounded by the fact that there is brake ducting as well. The ducts are also riveted to the bumper.

Pics of various parts of the splitter and how its attached.

The splitter itself should be separate from the front airdam and canards which are riveted to the bumper. Once you detach both clusters of (3) bolts securing the splitter to the splitter standoffs, the (2) outer bolts securing the ends to the airdam, and the (2) rear brackets to the aluminum reinfrocement plate the splitter should then come down. Often times the low profile allen bolt heads under the car will get scraped/damaged so you made need to use a cutoff wheel to make a slot in the bolt head and use a flat head screw driver to remove them.

thank you! I was literally just arriving at this conclusion myself. At first glance it looked like the air dam/lip has adhesive on it so I thought it was all one piece. Going to try dropping it later on today.

Much appreciated!
