The fuel/water plate is 16 gauge(?) steel, wanted it very rigid, and used .030 wire with the heat and wire feed turned down quite far. Did burn through in one spot, but it was correctable.
I was thinking of doing something similar, having the wing mounts extend back from the top of the diagonal bars coming off the back of the halo, more like a hatch back wing. That would put it forward of the rear wheels, perhaps balancing any down force better? Was looking forward to mocking it up, whenever my frame can get delivered!Hmm, like having a wing mount at the B-pillar hoop over the top of the fuel tank/diagonal bars area (generally speaking). That's a good point and the wing could definitely be in clean air, plus the down force would be applied at the center of gravity on the car (which is about at the back edge of the cockpit). That's something to think about - great idea.
Edit: kinda like this.
