What is the best way to take off the stock wing without damaging anything? Thanks

 

There are two studs that go through the back hatch that must be unbolted. Once you do that, slowly pry it off as it's held on with double stick tape. You may need to heat the area to soften the tape to help get it off.

 

Just like Dave said. I also used some strong test fishing line to help separate the spoiler from the body. Just take your time and it will come right off.

 

Or you can also use dental floss to cut the bond between the tape and spolier or body.
