Anyone know if this is a separate peice or not?
Pretty sure it is.
Approx 9 torx headed screws go through the black plastic scuff plate then the spoiler, and into the bumper skin, from underneath.
You can see/feel the screws if you lay on the ground and look at the underside of the lip...the bolts are either just in from the edge (25mm-30mm or so) or approx 80mm in.
EDIT: Damn...too slow.
