Rear caliper R&R
I have a new set of Racing Brake rotors and pads to put on my 2014 507. I started the project yesterday but didn’t get very far as before I removed the right rear caliper I wanted to make sure I could get a torque wrench on the caliper bolts when I put it back on. I simply could not find a way to get a torque wrench on either bolt that would allow me to put the required 135 ft-lbs on the bolt.
Can an anyone share how they have accomplished this feat? I tried disconnecting the top of the sway bar end link and that did not create enough room. Any ideas?

Take a picture, show the position of the bolts, vs wrench.
Can you put a 1" universal joint extension with a shallow socket on it?
Can you use a very long 1" extension and reach from the other side of the car ?
You CAN use an offset closed wrench with a 1" drive hole in it and put together some very simple math and adjust the torque wrench to a smaller torque.

Also, once the bolt is out, if you see blue residue on the threads, wet torque is different than dry torque. You need to know if the procedure calls the torque out with loctite, or dry.
If it's with locktite, I would buy their product from the dealer, it's not going to be a fortune and you are guaranteed not to mess the torque.
It's impossible to be 100% sure what the Affalterbach boys spice their threadlocker up with. As such, the friction properties may be something that they figured out in their prescribed torque number.

You can’t fit a torque wrench if you’re coming at them from the ground/on jack stands. You’d have to be on a lift. Wrenches are too long to fit in there. I’ve had my calipers off a few times trying to do the two-piece thing. If you’ve torqued your wheels, you’ll have a pretty good feel for 135 ft lbs and yeah be sure to use new bolts with pre applied loctite or clean and reuse originals. Don’t overthink this.
some better info here when I asked same:

Not sure. I think in this thread it was decided the rear caliper which mounts directly to the knuckle is 100ft lbs

I’ve swapped calipers before and I remember having to use extensions to come at bolts from a distance to give me some more working space. I also had to remove a sway bar link to just move it enough out of the way to give me even more room. Take photos of the bolt in question and I’m sure you’ll get better input.

According to Alldatatdiy the torque for the - Self-locking bolt, brake caliper to wheel carrier W204.077/277/377 is 115 Nm (85 lb-ft).

Hey mate,
What did you end up doing?
I'm going to be needing to remove my rear calipers to access the rotors and I had a trial run, my 1/2 torque wrench doesn't fit
Cheers!

Rear Caliper R&R
I ended up taking it a local shop. The only way I could see getting a torque wrench in there was on a lift. I am sure others here have managed it, but in the space I had, I knew I could get it off, but mot sure I would be able to properly torque it on re-assembly.
