do you mean 12 bolts per side or 6 bolts per side?

i will be using the rear brakes too, and the trailer brakes.

i am pretty sure I'll never have 24,000GVW, or at least not with this setup.

would it be strong enough if i had 16,000 LBS max?

how about the hub breaking? it is about 7/16" thick where the rotor mounts.

here's some pictures
