I've been looking to get the ford splitter or WC but couldn't bring myself to spend 700$ for a piece of plastic and then I broke my lower air deflector at the track

When I found the price for a ABS sheet there was no more question that I would make my own.
I used :
1x 54x106x1/4 ABS sheet about 140$
1x 48x96x1/4 corrugated plastic sheet for making the template 30$
2x longacre splitter brace 25$each. Found them here :

I used the 8" but they are too long. I had to cut them about half inch and move the holes on the support back half inch also.
Also you will need a support for the braces. I'm using the blowfish tow hook with the support built in.

First you have to remove your bumper cover from the car and separate your lower valance from the bumper cover.
Then remove the stock splitter and fixe the valence on the corrugated plastic.
Draw the line of your future splitter on the plastic
I marked a dot 2" from the wheel well on both side and then marked a line 4" away from the recession of your valance. This is the size of the World Challenge splitter. The Ford Racing one is 5".
Then connected my line with my dot using a piece of spring steel. So when you bend it, it form a nice radius.
Use your lower air deflector to mark the opening for the wheel.
Now it should look like this
Put everything back together to test fit it on the car
Once you are happy with it, remove your template and use it has a model to draw on the ABS sheet.
I used sink screw and nylock nut on every holes I could find in the lower valance. No push pin or J nuts
I also used a stack up of ABS left over to make spacers so I can screww the back of my splitter to the lower radiator support
Here's more pictures
Sorry for some of the Iphone crappy pictures
