It was just a lot of fitting cutting, the hatch of the car, cutting the base model spoiler that the RS spoiler bolts to, more fitting trimming and cutting, then the prep for paint. Honestly painting it was the easy part. [MENTION=879]D1JL[/MENTION] is preparing a write up on the spoiler install as he did a lot of the work mounting my RS spoiler to the base fiesta spoiler. It really is a cool looking part when it's all said in done. I almost feel like a ricer saying this but I swear it is semi functional and i feel it at high speed. (But that's probably all in my head)
I still plan to paint my spoiler like D1JL did his, with the base spoiler performance blue and the sides blue as well and the top center matte black. But that's not till I do some more Performance mods and other things higher on my priority list.
