January 3, 2009 - A view of the bracket on the new frame rail.
The new rails are 2x3" 18 gauge, which is significantly bigger than the stock stuff. Fair enough, there's a lot more running through them! I'll have lateral bracing wherever I can fit it, as well as a bit of vertical to stiffen things up.
After much measuring and poking around and measuring, it turns out that the correct height for the control arms is serendipitously right in the middle of the frame rail. I played around with heights ranging up and down a couple of inches, and this puts them 7" from ground level. That's 1" higher than the ones on Janel's slightly lowered Miata, making the geometry just about a perfect match for a stock Miata.
