The only thing I like about the SAP kit is the blacked out bottom chin, and I can do that more cleanly by painting it rather than strapping a piece of plastic to the front of the car that juts out with hard edges. Also, I just don't think the sideskirts are round enough for the car, and the spoiler just looks like an add-on off of another car (WAY too angular for the car - no line on that spoiler matches anything).
The entire kit installed looks OK with all the angles, but to me, the car's natural lines look more... natural. Plus, you have to pay a pretty penny for it... so I'm a no-go.
