I thought I would throw a small DIY together for this even though it is not too difficult.
Step 1: I used a fishing line to get under the factory lip spoiler, and went back and forth with the string the entire way across the trunk.
After the factory one was off, I was left with a lot of sticky tape. I just peeled it off by hand, it came off easily. I cleaned up the part of the trunk with a clay bar and some quick detailer just to make sure the surface was perfectly clean. Then I used a small amount of 3m adhesive remover (this is all I had, some people use alchohol) just to give it a final clean.
Step 2: Time to prep the carbon fiber with tape. I used automotive grade adhesive tape by 3m. It was a few bucks at Wal Mart so I bought 2 rolls incase I messed up. Notice the 2 strips I put in the back lip of the spoiler.
Step 3: I Heated up the tape on the spoiler itself with a hair dryer. I did this because I was in a garage in MN. I had the furnace in the garage on, but it was still only 60 degrees. Then I heated up the trunk surface. After all of that, I had 2 friends help me line it up and install the spoiler. It was relatively easy with one person on each side and middle. We got it perfectly centered.
Step 4: After you have made sure it is perfect, tape it down with painters tape. I used microfibers under the tape on the corners so it fit to the shape of the spoiler for maximum hold.
I let it sit in the heated garage for about 24 hours with the painters tape. Once I took it all off, it was solid as a rock.
