@Forged,

Do you mind if I pick your brains a little bit on the design here? I'm in a similar boat w/ Chris on current status/requirements and looking to put in a similar 4-point in the near future. Forged is a bit of a drive for me though (~13 hrs each way), so I'll probably use a local shop (undecided who yet). I've been trying to at least mostly sort through the design issues first on my own, so that I know what I'm talking about and what is or isn't acceptable when I start talking design with the shop (who I hope knows more than I do anyways, heh).

1) What was the logic on choosing this particular DOM size (1.75 x .095), does that just happen to hit a sweet spot for being legal for this car's usual class in a couple of different rule sets or other?

2) Is it possible to take the main hoop ends all the way to the lower floorboard as a design option when doing this, or does that just end up being a much weaker mountpoint than the obviously-strong spot you put them on that crossmember? Are there other pros/cons between those two spots, assuming the lower one is even viable?

3) What's the pros/cons on going with the harness bar offset to the rear like Chris's vs having it inline with the main hoop? I imagine your design is stronger (because in-line one of the two bars has to be cut and put back together), but is there more to this decision?

Oh and I guess (4) if you happen to know of a shop that's closer to Houston you'd recommend, I'd love to hear about it, would make my search easier
