it's not a body armor, mainly it's for on road use, strength of the material isn't important.

2 main purposes of if it

a.) blocking off fast moving rocks, debris. as you can see the small radiator has been hit before.
b.) reduce the salt spalsh during winter times. salt corrosion is one of the annoying things happens when you live in the salt belt. that's why I wanna make one in stailess steel.

the 5 flaired holes make the plate lighter, better air flow than a solid piece. but more importantly more rigid, because now the middle section becomes 3 dimensional.

I want add a stainless mesh/screen inside later on, that's why the holes were flaired outwards.
