My 99 Sedan didn't have a spoiler. I felt that adding a stock spoiler would be a good idea. Since I couldn't find a sedan spoiler I used one from a coupe. There is a difference between the two. You would have to see them side by side on sedans to really notice it though. Drilling the holes for a coupe spoiler on a sedan is interesting. It works though. Its about 3/4 inch shorter on either side than I would like it I think. It doesn't matter. Nobody has ever told me that my coupe spoiler looks bad on my sedan. Nobody has ever even noticed.
