STI rubber lip rubber extension and spoiler rubber extension
 

For those of you that have installed either of these STI rubber extensions... did you use screws/drill?

Mine just came in and they have double sided tape attached, screw holes, but no screws came with.

It's more widely known as a gurney flap.

Lots of info already in this thread: http://www.ft86club.com/forums/showthread.php?t=19836

It should come with two black plastic anchors that pop into the holes after you drill them.

Looks like in my haste to look through all the parts that came in I missed all of the plastic screws/clips... thanks!
