Torque spec for the 18mm caliper bolts

Anyone know what the spec is for these bolts. Got some new rotors coming next week and want to make sure I put the bolts back on tight enough. Thanks.

Anyone have the resources to make a spread sheet with torque specs for the commonly serviced items? Wheels, spark plug, brake components, filter cap, oil drain plug.

rear pad carrier to wheel bearing carrier 50 ft-lb
brake caliper to pad carrier 22 ft-lb
brake fluid hose to caliper 18 ft-lb
brake fluid hose to steel line 9 ft-lb

I'm stuck on these caliper bracket bolts as well. My calipers are still attached and the car is only on jackstands so there isn't enough room for a breaker bar. I tried a 18v cordless impact wrench and it couldn't get it done. Why were these bolts so crazy tight from factory? Damn ze Germans.

There is room for a breaker bar, turn the wheel on the car so the caliper sticks out, you can't get the bar horizontal but you can get it to stick out the bottom of the wheel well, its suppose to be torqued to 88 ft lbs or about as tight as the lug nuts.
Gotta pay to play.
