55Nm for the rears for a SLK230/SLK320 (the r170.466 model on the list is the slk32 AMG, so that one is 115Nm)
the fronts SLK230/SLK320 if you need to do them are 115Nm
please note the shop manual states to always replace these bolts when doing the brakes as they are self locking... most places dont but PLEASE apply some thread locker on them (loctite blue - medium strength) which is removable. pop some of this on the bolts and tighten them to torque.... they wont come loose or cause an issue!
