Is it true that the old 911's have magnesuim lug nuts and that they should be replaced every 10 years? I thought they were aluminum lug nuts, and I've never heard that they have a shelf life. I have heard that you always hand tighten them and never use an air gun on them, due to the metal being soft enough that you can strip them easily.
I ended up getting a set for $50.00 out of concern, just wondering if I got rope a doped. Thanks guys.
