Does the rear lip spoiler require drilling for installation or is it just adhesive?

Also, who sells them online? mitsubishiparts.net doesn't list my color (GG).

 

OB, PB & WW are the only colors Mitsubishi list for the lip spoilers.

 

Just to update this thread:

Yes, the lip spoiler requires you to drill 3 holes into the trunk lid. However, you really don't have to drill. The holes are there more for locating and to make sure it doesn't fall off if the adhesive fails since it is an OEM component. Most people are DIY'ers so they can address a peeling lip spoiler before it falls off.

 

you dont have to, i just chopped the middle leg off and used tape to attach it
