i'm wondering about that too, not the tray is plastic so it'll flew pretty easy, but on the final version, it'll be an aluminum sheet framed by small aluminum L beams...that'll be pretty stiff.

i'm also wondering if i might need to design an radiator air exit duct in...i might just get away with a top grill block, but the grills are pretty exactly sized, and it doesn't make sence to try and smooth out the airflow under the car and at the same time obstruct the flow trough the car, wich already had a hard time.... or would that needlessly complicate things?
