If one were to ever remove the splitter in order to resell vehicle, how obvious will the holes be in the bumper? I can see using the bolts to fill the holes but can they be seen by the naked eye while looking at the car on a level plane? Mostly worried about the outer bolts on the outside front edge and the front leading edge of the fangs. This is my biggest worry if I ever remove the splitter. Don't want to kill resale value if I install.

Here's the hardware list that I compiled (excluding the two extra moly bolts that Chris personally used):
You can pretty much get whatever nuts, bolts, and washers you'd like, but I went with what Chris used, which I'm going to list off the top of my head as follows: - Ten 1/4-inch diameter by 1-inch length machine screws/bolts (with 20 pitch threading) for mounting of sides of bumper/splitter - Ten 1/4-inch diameter (with 20 pitch threading) lock nuts for locking the bolts in place - Twenty 1/4-inch diameter inner hole by 1-inch outter diameter washers; one washer on the bumper side and one on the splitter side - Three 1/4-inch diameter by 2-inch length machine screws/bolts (with 20 pitch threading) for the center mounts in between the fangs - Three 1/4-inch diameter by 1-inch length metal spacer to help keep a healthy distance between bumper bottom and splitter top - Three 1/4-inch diameter (with 20 pitch threading) lock nuts for locking bolts in place - Twelve 1/4-inch diameter inner hole by 1-inch outter diameter washers; one washer on bumper side and one on the splitter side. And one on each side of the metal spacers as well. This allowed me a total of 13 mounting locations excluding the two support rods which I don't particularly want to use. Will see how the splitter behaves prior to tracking it, and see if they're absolutely mandatory. |

Chris,
A question: How did you ensure that the middle of the splitter fit flat against the plastic undertray and not start to ride down the hump? Edit: disregard. Last edited by Shipkiller; 02-11-2011 at 09:16 PM.. |

Excellent DIY Chris! Really appreciate how much time and effort you put into these kind of things.
It just occurred to me that I may as well just lift the cover off my car, remove my bumper and install my lip over the cold months so she is ready to go by spring... One thing though, I've never removed the front bumper off of our cars, is it hard, easy? Anything i should look out for or be careful about?

If it were up to me, I'd just buy all-new fender liner push-pin tabs because they're a pain to remove sometimes and it's quicker to just yank them out, possibly destroying them. The bumper removal DIY can be found here: http://www.zpost.com/forums/showthread.php?t=79994 The part that I'm referring to is step 1 in the DIY. These push-pin tabs are annoying. And so are the bumper's side mounts. Oh, and I forgot the few 8mm hex screws at the bottom which also serve to hold the bumper in place a bit. |

The DIY is complete now. Hardware, parts, & installation have all been updated. For the fender liners I ended up using a re-usable plastic fastener from BMW. I also had a hard time with the original plastic rivets Thanks again
