Pretty sure it's 19mm

19mm or 3/4 in a pinch.

19mm– yes that's correct.
I have a related question, without spacers of course. Are all the lengths the same for the Porsche wheels? I have Sport Carrera wheels with summer tires but just got Carrera IV with winter tires - are same lugs fine?

get a torque wrench and a special lug that has nylon on the inside so you don't mess up the aluminum lugs. I believe 97 ft pounds is correct torque.

I believe that for factory wheels and most aftermarket for Porsche wheels the lug length is common, without spacers as you mention.

I use 96 ft-lbs FWIW.

Thx for your responses. BTW, isn't 95/96 ft-lbs a tad high? Ferrari recommends 75 for my F355 GTB but many Fchatters recommend 85 (which I torque to) - extensive discussons there! Don't want to mess up the lug threads by over torquing! What does the factory recommend and do I need to torque higher for tracking?

96 is the factory spec for my car. '07 997S

Thx pcardriver. You've been a great help. This is a great forum.

My MY09 manual lists 96 ftlb./130Nm as the tightening torque for the wheel bolts.
