I know the typical Audi lug bolt is about 90 ft-lbs.
The only reference I can find online for the Q5 mentions 105 ft-lbs but that reference also shows the use of antizeize on the threads which is a no-no.
To confuse the matter more I just used an old torque wrench to loosen the factory bolts and I get about 75 ft-lbs.
Anyone have the true spec? Specifically for the SQ5 if that makes a difference. spijun ?

My Audi manual states 105ft/lbs. I can't see the SQ5 being any different.

Generally I agree. Just weird it was 75 coming off. I wasn't sure if the SQ's aluminum hub rotor makes a difference.

MP4.2+6.0

1. If the rotor hats were that sensitive to pressure evenly applied by a wheel face being bolted to a hub with a rotor sandwiched in between, think of what happens with the dynamic forces of a wheel and suspension being slammed by all manner of potholes, road junk, etc. and being resisted by over 4000 pounds of vehicle, probably 1200 or so pounds of which are at each front wheel. And of course, the wheel itself is cast aluminum held by the usual five bolts, as has been typical design on Audis for years, including many similar weight ones with the same hub set ups, bolt patterns, etc--A8's, A6's, S6's (heavy V10 motor on the old S6 particularly), etc.

2. Same sort of rotors used on base A8's now (where they came from in the parts bin). Can look there. Can find overlapping but fancier flavors with RS4's, RS5's and various M's for that matter. Never heard of any kid glove bolt torquing elsewhere either.

3. Doesn't compute they would have a separate spec, and if so then what--one for the aluminum hat fronts and another for the plain Jane std. Q5 issue rears?

It's another Audi in the end. Std. specs make sense for safety and otherwise.

According to this there is no difference for the Q5 and SQ5

My 2014 Q5 owners manual also says 105 ft lb/140 Nm
