I have just purchased a 2007 911 GT3 (997 Gen 1) with the standard GT3 19inch wheels. The manual recommends 130 NM of torque, but someone at the dealership told me that Porsche subsequently changed that recommendation to 160 NM...that seems like a huge change, and before I tighten them to that number I thought I had best see if anyone can confirm that! Thanks.

Ben, nice ride by the way.

I finally drove a GT3 today, courtesy of Ben.................. :dance:

I have avoided it for a long time, as I simply "didn't want to know". In short, fantastic. My closest comparison is my brothers 996TT - the GT3 a much sharper scalpel!

Oh, by the way, his cab is fantastic too (a very long story on that one!)

I was able to get the Porsche Service Bulletin that addresses this issue and have found out the following: Porsche specifies a torque of 160 NM for silver or black wheel bolts on sports cars as of model year 2012. For cars up to model year 2011, a torque of 130 Nm is allowed, "160 Nm also permitted retroactively", but it appears any "black wheel bolts" regardless of model year should be torqued to 160 Nm. You may find that your Porsche dealer is torquing everything to 160 Nm just to keep things simple, and FYI, I am keeping my torque at 130 Nm simply because of a lifelong fear of "over torquing" wheel bolts...and it seems Porsche is saying that is "ok".
