You mean 80 ft/lb for the longer black bolts that go through the caliper to the bracket and 60 ft/lb on the shorter silver bolts?
The opposite.

The shorter bolts hold the adapter to the hub, stock torque specs is 80 ft/lb for the caliper carrier bolt into the hub.

The longer bolts hold the caliper to the adapter. The caliper is aluminum with the aluminum adapter so it not designed for as much torque. I used 60 ft/lb for that.

With locktite on both, they should not come loose.

Edit:

I found a DIY for the Build Journal kit which uses the same hardware. Looks like I over torqued both bolts. They say 50ft/lb for both bolts. Trimming of heat shield was not necessary for e92.
