"Why not use a USA rack to start with?"

Because the length of the rack was dictated by the inner pivots of the lower control arms. And I am obsessive about suspension geometry.

Find me a stock front-steer rack with 22" separating the inner tie rod pivots and I'll change in a second. The Subaru was perfect when we first started using it some tweny years ago. Light, strong, cheap, and dimensionally correct. I've looked and looked, but have never found a suitable replacement. We did not want to force the customer to buy from us, so the rack had to be off-the-shelf.

"I did find out that the ERA rack is a Flaming River rack that is modified by ERA but I can not get an answer as to what they do to it. "

The rack, pinion and housing are shortened, the mounts cut off and new mounts machined. It's a PITA to do.
