Torque spec for centerlock rotor hardware?
My oem rotors are toast so I'm going to install new oem front rotors myself this weekend.
I purchased new hardware for each, so does any one know what torque specs (if any) are specified for the fasteners of the pins under the sleeves as shown below...

Threaded connection securing wheel to wheel hub, M14 x 1.5 Thinly grease thread, shank and under head (between screw head bearing surface and spherical cap ring) of the wheel bolts with Optimoly TA (aluminium paste). Do not grease bearing surface of the spherical cap facing the wheel. If heavily contaminated, clean the bolts first with a lint-free cloth. Tightening torque 130 Nm (96 ftlb.)
Wheel to wheel hub/central bolt All contact surfaces of the wheel, wheel hub and brake disc as well as the trapezoidal thread in the wheel hub must be free of abrasion, sand, dust or chips. Apply some aluminium paste (Optimoly TA) on the trapezoidal thread of the wheel hub if necessary. Grease the conical surface of the central bolt with a very light coating of aluminium paste (Optimoly TA) before fitting each wheel. For advanced grease specifications (which are only necessary under certain conditions), refer to the description Removing and installing wheel with central bolt. 3-step tightening procedure (Step 1: Tighten to 600 Nm (444 ftlb.). Step 2: Loosen the central bolt again (slightly) by approx. 60 angular degrees (1/6 turn). Step 3: Tighten to 600 Nm (444 ftlb.)). The tightening torque was increased to 600 Nm (444 ftlb.) (previously 500 Nm (370 ftlb.)) in the course of model year 2011. The higher tightening torque also applies to older vehicles. 600 Nm (444 ftlb.)
