This is my photo and it's actually a 4". I sand them down and primer them before i paint them. They work really well. And only $48. Some people even think mines made out of a composite because I sanded it and painted it so well.

 

How did you mount it to the car?

 

Devsport brackets and just 2 turn buckles. No idea how to post photos or I would. Very solid. If I have a massive off it'll splinter and break just like I want it to. Weighs about 6 or 7lbs.

 

How did you create the outline, draw round bumper then add a couple inches?
If you can post a picture of the hardware used that would be awesome!

 

This is how almost everyone's splitter is mounted:

For Dave's we traced the splitter in the thread above, but if you don't have access to one just trace the bumper and add as much as you'd like.

 

i was looking at the quick release version of them and then i was going to put to bolts in the back of the frame with a spacer so that way it will fit snug in the back and add support but can easily be removed if broken or needing the clearance to get on the trailer.
