Fabricated A-Body spindle ideas and discussion

The above layout is still using the Scat Pack caliper and rotor info. I don't have any of the needed S197 info and I'm not sure the nut needed for the LBJ bolts would fit between the caliper mount plate and the hub. The SP rotor has a depth of 58mm overall and the Mustang one is 46mm. That's potentially a 1/2" shorter on the spacer assembly and the current setup only has 0.338" before the nut is into the hub. Not saying for sure that is the difference in height, the caliper can have a large impact on this. Just guessing right now since I don't have an info.

My thought right now is to forge on with the SP stuff and if I want 15" brakes I will use GT350 calipers and an adapter that does from the ears to a radial mount caliper. Not going to be off the shelf, though.

And I think the SP setup is the better one anyways when compared to the S197 4 piston setup. Where the S197 setup shines is being able to easily upgrade to 15" brakes, the SP stuff only really has the HC option and that doesn't fit under 18" wheels.
