I have a 2007 Hardtop (Coupe I believe). When the rear spoiler is in the up position (raised) there is a black plastic cover underneath. I want to get that carbon fibered but I do not know how to take it off. I went to the manual and could not find a step by step on the removal of that underneath cover. I found the screws holding it down but it still does not come a lose from the body.

Can anyone help me out here
