Hey all I need your feedback as I want to do it correctly for my ebay brand which does not come with any instruction for putting it in a correct/perfect position. So when trying to mount or position the Rear Roof Spoiler - Do you position it so it align with the glass while leaving a tiny gap/space or do you align it close to the roof body so no gap and possible touching the body? I hope this make sense lol.

I think it looks better align with the glass but I'm not sure if that is the right way or is it a preference?

 

 

I left a gap on mine, its right on the top edge of the window... 3m tape holding mine down as well - make sure you get some 3m adhesive promoter and hit the area that the spoiler will be sticking to. I left 2 cases of water on top of the spoiler overnight to ensure a good solid bond to the back window. Make sure to leave room for water to get out
