Alright I thought I chime in here, I am no expert, so I will give some images for ideas
Firstly we just purchased a Chevy Traverse a couple months back. This 3 row, 7 seater (4700lb!) is currently getting 22MPG with my wife driving. (With the roof racks, don't ask)
First, I am hoping to provide an insight as to what the manufacturers are doing in this area. My attempt is second
First is the rear spat:
The fronts do not have any, it seems Chevy is relying completely on the front air dam, for that.
And now my vehicle, I used one piece of (the best I can describe it) a carpet stair tread corner protector
I decided to go about .25 inch wider than the tire, then attach with stainless screws.
Scrap left over:
Installed angle one:
Installed angle two:
Just hoping to provide ideas, if anyone has comments, I'd love to hear 'em.
