The triangular black piece that connects the bottom of the wheel well to the bottom of the front bumper....I also heard that you can go without the splash panel...but it isn't recommended. Is this true? I have the main bumper and the bottom lip that I bought from a friend but I still need to get the other pieces to make it work and I don't want to buy too much stuff if I don't really need it. So far I need all of the impact strips, the lower grill, the air ducts, the transition pieces, and the splash panel(if needed). All of that is going to run me about $300 on bavauto on top of the $250 I paid for the bumper + lip. I'm thinking that maybe I should have just bought a M-technic Kit from bavauto because I'm only saving like $50....and maybe some saved on shipping.
