Steve,
Ok, I read your profile and I know that you are not stock and you do have rims, so I am assuming you are already lowered. (If you're not, do it now.) Personally, the WingsWest piece, throw it out. It looks like you will trip over it when you walk by plus it looks kinda cheap in that pic. The Greddy looks decent and I actually don't mind the 'air ducts' on the side of it. But I think the stock one looks a lot cleaner than the aftermarket ones. It looks like your car is the dark green color (according to your avatar) I think you should see if they make the Greddy lip or equivalent in carbon-fiber, it would contrast your car very nicely.
Oh yeah, it'll probably crack/break off in about a month. Good luck.
