With the maintenance done, I could now install the undertray. This will be in four sections.
Previously, I had installed some "framing" for the coroplast to screw to. It was framed on 48" centers and held away from the exhaust and moving components. The undertray will not cover the cat, but will cover the exhaust. I will install a diverter in the tunnel to deflect air from going down the exhaust pipe tunnel. The framing is steel firring framing pieces. They are straight and easily take sharp screws.
The four sections of undertray are:
From diffuser to the rear side of the sub frame,
from the nose to the front side of the sub frame,
then the sub frame cover (two pieces- one on either side of the cat.
I took the undertray 4' by 8' corroplast and sandwiched some metal sheet rock corner beading on both edges. Now I can screw the sides of the undertray to the framing and there is no danger of it pulling out of the coroplast.
Finished rear piece tied up under the diffuser. Attached to the metal support bar I previously installed.
and the front undertray tied to the bottom of the bumper neatly. The seam taped with Gorilla tape.
Now I can remove my hokey air dam made with 6" lawn edging. It would scrape.
