I've been searching about this and can't seem to find much info about it, the M Sport style bumper i'm talking about is this one:

I was wondering, do I need to still purchase 100s of extra pieces like the M sport ducts, belly pan, fender liners, or is this bumper made specifically to fit the non M sport cars like some of the ebay ones. PS those who bought this bumper, hows the fitment?
