How to: Mach 1 lip install
Supplies needed:
Mach 1 Lip Here
5/8 self drilling sheet metal screws
Cordless drill
Something to cut plastic with.
Step 1:
Pull lip out of box and allow it to straighten out in the sun. It comes folded in 3 peices and its kinked badly.

Find the screws you want to use. You can use anything really, but I used 5/8th's long self tapping sheet metal screws.

Step 2:
Locate the center of the lip. It is easily marked by the center hole(non slotted)

Step 3:
Make a releif cut. This is necessary because the z04 bumper comes to a "point" where the mustang bumper is one smooth curve. You dont HAVE to do this, but in order for it to look decent I reccomend it...


Step 4:
Center the lip on the bumper and install 3 screws. 1 in the center, and one on each side of it. This is crucial that you get this perfect. Keep the lip back about a 1/8th of an inch, the z04 bumper has a rounded edge and it dosent look good up flush with it.

Step 5:
Begin working your way out from the center installing more screws. Keep working the lip with each screw making it fit with the body line of the car. WOrk your way out to the corners then move on to step 6

Step 6:
The corners also need releif cuts to follow the body line properly.
Here is how it looks with no cut, you may be able to make it work, but I prefer just to cut it.

Make a cut like this

I actually made 2, but I didnt get a pic.

Now line it up with the rest of the bumper and screw it together

I was able to slide it under the factory z04 lip that wraps around and meets up with the ducting under the car.
Now do the same thing to the other side.
You will probably have gaps and alignment issues. It took me about an hour of tweking to get it aligned and get rid of any gaps.
You can use a few screws in the front of the lip to make the curved edge of the z04 less noticable

Heres the finished product:

Re: How to: Mach 1 lip install
These have grown on me when properly installed on nice looking cars.
Did you have any smile prior to the install? If so it looks to be solid now. I know a guy that I need to pitch this idea to.

Re: How to: Mach 1 lip install
Added weight for the Baims mobile? I've thought about adding one to my car too. It's a little on the ricey side, but I do like how it makes the front of the car look lower.KFLO 93 GT wrote:These have grown on me when properly installed on nice looking cars.

Re: How to: Mach 1 lip install
If I had one of these it would be
... I've noticed a properly supported lip will clear the typical curb height, and parking block size, even when the car is lowered... If this was on my car it would have been hit more than once and wrecked my lip in the process I'm sure.

Re: How to: Mach 1 lip install
My bumper was sag free before this lip instal. It will not support a lip, it is very flimsy.
My mach 1 lip is not broken in 2 pieces and zip tied back together. It is not winter friendly. It needs to be removed when the snow tires go on.
