When tightening the aluminum lug nuts, what is the right amount of torque to use? Are they easy to break? Is there a special "tool" that doesn't scratch the finish? Thanks.

Griot's sells these for $59.99



but I have always used the standard lug wrench and never had a problem.

95 ft lbs. Check out <p-car.com> for addtl specs, reference, information, data, etc.

There are a variety of nylon lined sockets on the market that claim to reduce scratching. Automotion and others have them. Around $20.

I use 94ft.lbs. Just make sure your torque wrench is *calibrated*. You'd be surprised at how badly 'off' the cheapos are!
Also, the numerical value (94) applies to DRY threads. If you lube up your lug-nut-threads or put any sort of fluid e.g. graphite then all bets are off. I believe (but you should check) that if your threads are lubed then you DECREASE the amount of torque applied.

Thanks. I appreciate the help. This is the first time I pulled a wheel off the car and was astonished at how light weight the lugs were. I can see how easy it would be to screw things up...

Actually, the wheel torque specification is 130NM or 96FT/LB.

What's one or two ft/lbs between friends.

Would this apply to Ruf wheels also?

I thought the 96 ft lbs was when using anti-seize lubricant.

Actually Porsche recommends "clean / dry threads", they don't recommend using anti-seize.

Just make sure you use a deep socket. A shallow socket can literally twist (or break off) the end of the aluminum lugnut.

I use a standard impact socket with some blue painter's masking tape wrapped around it to avoid scratching the wheels. However, the black has long ago worn off of the edges of the lug nuts themselves.
