It's probably less of a factor in stock form, but I want to eventually have the bottom as flat as I can reasonably make it.

The under panel improves the rectifying effect on the bottom surface of the body during high speed driving and generates downforce.
Also suppresses the flow of air caught in the engine room.
By installing a ventilator, it efficiently discharges the heat of the engine room and prevents heat up of the engine.
We also made use of 2.0 mm thick aluminum material for weight gain.

It's certainly smoother than the DIY posted above.
