E36 BMW M3 LS update.

I had a little time to start on the underside flat bottom aero.

This is one side of the aluminum frame that will bolt to the underside of the car. It's 1"x1" x1/8 6061 tube.

I'll make both sides and lift em in with floor stands and get it all level with the laser. Then drill the frame and the shell for mountings. Mounts in the car will be M8 weld nuts and the frame will get crush tubes welded in for countersink hardware, so the belly pan can bolt to these frames with countersink hardware into nutserts in the frame.

Weld it up then make another.
