I know many have swapped the calipers around side-to-side on the rear so the calipers are at front, mine are still at back. At this stage I'd prefer not to disassemble rear to do this, but I will if I have to.

I also only just realized that FFR don't supply rear brake line, so I'll be looking at build threads today to see how others have routed when caliper is at back, and if it's a "nice-to-have' mod or a "you-really-should'. Also what do people use for the flexible lines - stock mustang part (remnants shown below) or fancy. Seeing the budgets available to many here, I expect lots of fancy $$$ solutions, but I'll take a good working solution if you have a suggestion.

I did buy new replacement rotors and pads; one of summit's "Street Warrior Z26 Brake Kits" packages: https://www.summitracing.com/parts/PWR-K1303-26
