Default Cusco Underpanel - Custom

Instead of buying one from Cusco, I have decided to make my own in class. Made from 1/8" 5052 Aluminium and tig welded together after the center section was bent. Not completed as I still have to finish the welds on the center side gaps and get the holes drilled to mount. Not bad for first attempt at welding aluminium

Looks like it will become an intake scoop of some sort. I'm curious as to the ground clearance with that scoop.

It creates a low pressure spot so when the air goes under the car it pulls down on the front of the car.

Ground clearance will be the same as current with the bumper, plus 1/8" for the underpanel.

I fabricated two small brackets that hang from the radiator support. Basically two small strips of aluminium and drilled holes at each end to mount to the horns and the radiator support.

Exactly. My hole is smaller in length than the cusco but also a bit deeper. Hopefully it works similar.

If that is the case I am assuming it's mounted so the box goes down creating a neck down affect between it and the ground.

If that is the case look at the ramp angle on the backside so you don't get detachment of flow or your ruin the affect of the aero.

Did a 70 mile run on a country hiway, speeds up to 80 mph, seems to actually pull the front end down, steering felt stiffer. Want to figure out a better way to mount the front of the lip to the bumper, right now its sturdy, but I need it to be solid if I am going to go over 100 mph.

Thought about that but since it is now only held on by subaru plastic clips, I wasn't sure how much force it could handle before coming off below the car

Be careful to make sure you are getting enough cooling with that undertray on. I have a splittler/undertray that starts 6" in front of the bumper and ends just ahead of the wheel center line that caused a significant increase in engine bay temperatures.

I ended up having to duct the radiator to the bumper to get enough air flow to keep it cool.
