Z4 Aero side skirts part #s

Got the Aero sills installed......
It's a straight forward install, but thought I'd post a couple of points...
Removal
The external fasteners are obvious, & the first thing to tackle.
Once the fasteners are off, pull the OE sills straight out where they join the body (at the top edges front & back)
Then...slide the sill forward & it will come right off the hidden bayonet fasteners.
- clean the nooks & crannies thoroughly
Then remove the female part of the fastener from the body.
(the bayonet fasteners are one time use... new ones come with the sills)
Install
Transfer the weather strip from the OE to the Aero sill. (just pulls off)
It has some butyl inside & reseals just fine to the new sill, no need for more goop.
Install the *new* bayonet fasteners on the sill (c/w the female portion)
!!! before installing on the car!!!
You will likely have to trim the sill a little.
..right here at the back edge. (look at your OE sill & you'll see the difference)
- Then just snap them in place with the bayonet fasteners.
after snapped in, you can adjust alignment fore & aft by tapping the sill in the appropriate direction.
When aligned install the external fasteners & you're done.
