The 4-point Forged put together turned out pretty awesome.

I'm getting closer, I've stripped down my car from the backs of the seats on back and all of the side-plastics in that area, but not the headliner. Been staring at it for a couple of days and reading up on various rules and regs and safety issues so that I at least have some idea in my head what the right design should be. Then I'll head to a local shop or two and see if I can find someone I'm comfortable with to do the work (Forged is a bit far heh).

Got a couple random Qs:

1) What was the idea behind standing the harness bar off to the rear like that? Most I've seen keep it in-line with the main hoop? Just to avoid the X-shaped intersection with the diagonal and inherent weakness that comes with chopping one of the bars for that intersection?

2) Where you put the bottom mounts of the hoop makes a lot of sense, and seemed like the best option to me when I'm looking at mine as well. But, was there any argument though, for moving the legs forward a few inches and going to the lower floor (level with the bottom of the seat rails, in other words)?

Seems like it would possibly cut into your seating space (moving the seat forward another inch or two) to try that, but on the other hand the spot you've chosen makes me wonder about adding lower door bars later, or directly mounting seat rails to square-tube floor extensions from the cage (both seem easier with the main hoop going all the way to the lower level).

3) Also, what was the factors that went into settling on 1.75x.095? I've been waffling between a few different dimensions of DOM looking at different regs and things and hoping I don't have to rip out my 4-pt a year or two down the road just because I end up trying out some event/series or other with different rules than I expected.
