From my 997.2 manual
Always clean the wheel bolts before fitting. Apply a thin coat of Optimoly TA (aluminum paste) on the thread and between the bolt head and movable spherical cap ring.
The bearing surface of the spherical cap facing the wheel must not be greased.
Tightening torque 96 ftlb. / 130 Nm

Silver wheel bolts (up to model year 2011) = 96 ftlb. or 118 ftlb. also permitted retroactively.
Silver wheel bolts (as of model year 2012) = 118 ftlb.
Black wheel bolts = 118 ftlb.
Center Lock wheels - 444 ftlb. (that's right four-hundred-forty-four foot pounds.)

Per my post on another Optimol thread, the Castrol people and the Loctite (Henkel) people are very nice folk, and will answer your questions. They understand their own and their competitors products.

Three Wheelin'
Does anyone know why Porsche changed the torque spec on wheel lugs from 96 ftlbs to 118 ftlbs ? The techs at my dealer said this spec is also retroactive to earlier years of 997 not just 2012. I am putting after market wheels on for winter and wonder if I should use 118 or use the old spec of 96 for these wheels. This spec also seems to be not just 911 but Cayenne, Boxster, Panamera etc. So why the increase were wheels falling off?
