I have installed the WingsWest kit on my car in the past and I can tell you that the fit is NOT "excellent" IMO. The best fit and easiest install is that of the front air dam. The side skirts and rear spats are far more difficult to line up. The rear spats, IMO are the wrong shape all together. They just don't fit the car that well. The best you can hope to do is get a good compromise between having the skirt installed too low on the car or having the skirt angled outward at the bottom. FYI, I have the front air dam and rear spats on my car now along with the Marga Hills style side skirts and the car looks great. Just recognize that you will be spending some time with the WW stuff to get it to look right. The side skirts are often shipped in such a way as they arrive "bent". It takes some time for them to come back to their original shape. This is per a converastion with a body shop owner who has installed several sets of these skirts. Hope this helps.
