I used aluminium sheeting leftover from a cladding job at work. It's about 1mm thick and is quite light although a full car undertray might weigh a bit with all the fixings included. I just covered under the engine and from the back axle to the bumper. Improved coast distance noticeably but cabin ventilation is terrible. The exhaust vent is in behind the bumper and vents out in the space behind the rear wheel. I had to install some flexible ducting to continue it to the undertray but is still not good. Windows fogging up a lot. Anyone have any ideas how to make a passive exhaust vent?
