Fabricated A-Body spindle ideas and discussion

There’s a lot here so far and I want to make sure I’m tracking with parts selection. So far the hub is S550 with SP calipers and rotors? Hard to tell from the back and forth but is there a preference toward Mustang parts but unsure if they’ll work because we don’t have measurements to confirm? If so, I’ll order a caliper and rotors and send them to you DionR, if it works awesome, if a no-go because of the steering arm, then we know and can move on with knowledge.

Correct, my model is currently laid out around the S550 hub and SP rotor/caliper.

Yes, there is a potential benefit to the S197 rotor and caliper. Upgrades to a 15" package are easy, they seem to have worked well in their application, prices aren't bad, they are probably a touch lighter than the SP setup and they should (in theory) fit the hug with no slope (the center bore on the SP rotor is bigger than the pilot on the hub).

The rotor info is easy, don't need those to measure from. It's just the centerline of the rotor to the mounting surface of the caliper that I need.

I would hate for you to spend money to send me a caliper. I hadn't thought about it until now, but I could buy one and return it after getting the measurements. There aren't any that I find locally, but I can order one from Autozone with free shipping and return it to the store so no one is out money.

As for machining, once we have a design, I’ll send it to my guy and to Michigan Metalworks to get other pricing options.

I could setup a model that uses a machined spacer instead of the sheetmetal one. It would probably be a different shape than the one I have right now so it would be a different design.
