I wish I could just cover the entire car in the stuff just to hide the shadetree paint job.

I piled on all the missing parts and materials and it came to 1900 lb wet. I added in an extra 25lb for the stuff I did not have in hand or thought of yet like the bar padding.
Overall I think there is about 100 pounds of safety related weight that was not "required" but I wanted.

The braces are 1/4 inch thick aluminum and tightly clamp bolted but would not be much help in a wreck as the ends would fail. They are just added stiffness across the top of what was otherwise and open box. Kind of like a shoe box with no lid will deform easily but not so if you tape the lid on.

Required or not the right side net helps keep you in the safer angels zone in an offset hit. I jiggered my left side net system to do some of the same. Much of what a right side net does is guide you BACK into the seat after you deform and extend out of the seat past the side bolsters and head halo if present. that is why they must be tight to the seat sides. Too many that "pass" are too loose IMO and can be pushed out of place. This reduces the nets guide back and H&N system helping ability. I think your body would displace the net unless it is in right and tight during the impact and this adds complexity to the G forces. Complex G forces are very hard on you. Clean on/off G loads are surpassingly well tolerated but jagged whips and snaps much less so.

LMFAO till I cried ... others near me in the cube farm started moving toward the emergency entrance. Guess they thought I could be wigging out and might be packing.

watching this build makes me feel so inadequate. Will this specimen be on display at Porkchopfest?

I went out with Kurt to pick up what turned out to be the mulch-filled 77s from the storage yard. Lets just say it had been in need of some attention for some time. Its been a real experience to watch the transition from an unwanted heap to what you see in the pics below.

If I remember right, the passenger will be sitting yoga style, facing backwards about 3 feet behind Kurt, on top of the engine.

Not exactly, but not far off, either. It will work better at the clockwise tracks (most) than the counter-clockwise tracks (e.g. Shenandoah) because you'll basically be looking out the passenger side window. I say "you'll" because after the TR look-alike comment, I may not get the chance... (and in reality it was inverted colors, kind of like those aliens on "Star Trek").
