The other parts can be found on REALOEM.com when looking for the bumper trim section for the 4.8is model. All of my parts were sourced on Ebay, Morristown BMW, and getBMWparts.com. The proper installation process (not glued) for the fender flares isn't easy...a dremel tool will be your best friend.
