In the aerodynamics package, how does the OEM wing attach?
Rather, how do you attach one after-the-fact. Is it's double-sided on? Is there a template for precise placement?

 

The stock "wing" is held on by double sided tape and two bolts. I do not think there is anything for a "perfect" fit. From what the dealers say, all the rear wings are in slightly different spots. So adding a aftermarket spoiler is tricky sometimes.

 

To be fully correct....The stock wing is held on with two screws and two clips. That being the case, there are 4 holes across the rear deck lid. The outer two are for screws, the inner two are for the plastic clips, and then there is double-sticky around the outside to seal it on and prevent movement. As for template, I don't think the wing comes with one, but you could probably make one by using the same paper that clothing patterns come on.

 

is there a way to add the oem spoiler without drilling holes? any speciific adhesive or somehting?

 

I used 3M moulding tape only. I did not use the tape that came with the spoiler, it looked inferior to the 3M tape.

It has held fine for 6 months here in Georgia. I'm not sure if tape only would be okay for an ice and snow environment.

You can easily position the spoiler by using masking tape. If you put 1.5" tape on the sides of the hatch, it helps center it left to right. As for distance from the bottom of the hatch lip, measure and mark using a grease pencil. I positioned this to my preference.

Now if you plan on drilling holes, you must be more careful. Remove the plastic trim from inside the hatch, and you will see what I mean. The screws must be located precisely. I can't help you with advice here, because I chose not to drill.
