Would it be a huge deal to switch out a rear lip spoiler for the stock wing type spoiler that you see on many mazda's. I just got my new 2005 mazda3 sedan and wanted to get this changed out.

 

I'm guessing the hardest part will be removing the lip spoiler. It more than likely is attached by 2 sided tape, so just slowly peel it off. As for the Wing spoiler you can get a stock style spoiler off ebay for less than $100 painted and the color match is great. They send a template with it, so all you do is drill 2 holes for each side and put on washers and bolts and tighten. Nothing to it. Good luck.
