Here, the roof cut is clearly visible. The roof is not cut in the middle, to widen and lengthen it. Instead, the windshield is laid back, as already described, and the side windows are tilted in more. This means that I haven't had to do any welding in the middle of the roof, which is nice. The rear hatch and the rear window are also stock. The entire roof has been tilted forward.
With most of the temporary bracing of the roof taken away, it starts to look more like a car. The lines are starting to show!
The roof cut is welded up.
The lower part of the stock A-pillar is connected to the roll cage.
The C-pillar is being built up again.
Again, in the interest of having the cage as invisible as possible, and making the car as stiff and strong as possible, I decided to place the main hoop between the outer and inner sheet metal of the rear fenders. It also gives more room for the seats. This meant I had to cut open the door jambs to gain access to the area in question.
Since I will not have any roll-down door windows, I welded the gap in the top of the doors shut, stiffening them considerably.
Although the car has surprisingly sturdy door beams, I decided to stiffen and strengthen the doors even more by welding sheet metal between the inner skin and the door beam. This is possible to do, since no window will ever again go down here. This is in the interest of safety, which I am a big fan of.
The front of the cage will intrude on the door space, for reasons I explained earlier, so this means that the door has to be cut up to accommodate the roll cage tubing.
Here's a close-up of the cut-out.
