CL wheel reinstalled without 1/4 turn backoff. (991.1 TT 60K miles)
Had a slow leak fixed at a Porsche shop in NC. During the 100 mile drive home it suddenly occurred to me that the mech didn't tighten the wheel with the torque wrench and then loosen it a 1/4 turn and re-tighten. Opinions please on how serious this is. 100 miles later do I now back it off and re-tighten? If I just leave it will there be a problem down the road?? And if I have to now re-tighten can I do it with car on ground or do I have to raise the wheel. BTW car drives fine, no issues at 100 mph.
TIA

 

From my understanding it is a safety precaution. However if you are still alive now, go ahead and back it off and re-torque it.

Although not ideal, I am sure you can get away with the car on the ground, as just about every video shows people doing it that way.

 

More importantly, ensure the lock engaged.

 

i've never done the 1/4 loosen and retorque and never had an issue. there is a click lock thing that prevents the center lock from unscrewing unless its pressed in by the tool.
