Special thanks to: Jon for helping figure out the parts, My friend Bryan Odell (Master BMW Technician) for more information and some parts and the Murray Motors parts gang for looking all the part numbers up for me :)

I Bought all the parts from Pacific BMW, speak with Edward.

Here are the Before pictures of the front and rear:


Here is a shot of some of the tools you need:

On the front piece you will see tabs all around. I was going to try and cut groves in the bumper to accommodate these tabs but it proved to be a real pain (OK Jon you were right). So I trimmed all the tabs with my dremel tool. Make sure you leave the ones that attach the top between the grill supports (you will see what I mean in the picture). You will need to clean the bumper well with a diluted alcohol solution then take your windshield adhesive and put a good bead around the edge of the spoiler.

After you do this you can snap the piece in place. Use your tape to secure it for curing as shown below.

You can use "Goof Off" to remove any of the excess adhesive that comes out. Be careful though, this stuff can get everywhere. The cure time is 24hrs. for the adhesive.

Now for the rear. The rear is VERY easy. You will need to trim the tabs inside the rear piece so it will fit snugly on the lower portion of the rear bumper. There is a hook tab on either side of the rear piece as well that needs to be removed with your dremel tool. Do NOT attach the side caps yet. You will need access to the drill holes. Once again clean your surfaces. Then apply a bead of adhesive where you need to (you will see where during test fits). It will be helpful to have a friend hold the piece in place while you use a self-tapping screw to secure each side. Once those screws are in place get under the rear and add 5 screws to the underside. See pictures for more information.

Now you may install your side caps. You will not see them on my car above because they are still coming in :). You are now complete.

To be honest the front was the hardest. They rear went right on. I will try to post pictures of the completed product after the adhesive cures. I am also putting on the aluminum running boards later this week :)
