I'll definitely keep that in mind as an option. I'd ideally like to just use off the shelf components where possible just for ease of getting replacements.For the rear disc, I'm pretty sure you can get the FTO rear disc and have a brake work shop or engineering work shop redrill the hub from the 4x114.3/5x114.3 to the 4x100. As its a different stud pattern theres no issue with redrilling it, it'll all still be balanced etc.
Would that essential mean you could press in a 4x114 hub in place of a 4x100? Could be an easy option to change stud pattern no matter what route I go brakes wise.This matches my recollection, but I think if you separate the hub from the trailing arm you might need to replace the hub. I think it's a single-use press fit, and removing it may damage it; and I think that's why people say "just get the whole trailing arm setup".
Which, from the perspective of saving on interstate postage, might be a better saving anyway. If you're gonna get new oem hubs locally anyway, then they can leave those out of the shipment and just sent the brackets, dust shields, calipers, rotors, etc. And if you can get new oem rotors locally, that could be another heavy thing that doesn't need to be shipped interstate.
I've got a pretty well equipped workshop at home (been in the auto industry my whole life) so pressing hubs back in is not a stress, and I work weekends at Repco, so staff pricing helps keep costs of readily available parts down.
