For those who have been changing out their wheel bolts, are you applying any anti-seize or lubricants to the wheel bolt like the manual indicates? If so, what are you using?
<u>Guilty </u>of not using anything. All I had on hand was silcone grease and was not sure about using it for this application.

No Cayman for me till July, but I picked up some anti-seize at the local auto parts storethat I use onmy present cars. Depending on how much you get, it comes in a tube like toothpaste or a small bottle. I don't think the brand matters as long as it's anti-seize. Been using it for years on lug bolts with no problems.

I've always used anti-seize compound on the mating surfaces between the wheel and the car, but not on the threads. My understanding is that lubricating the threads will affect how the lug bolts torque down. I've also seen concern voiced over whether the lubricant would foster the lug bolts backing out. These could all be old wive's tales as I suspect whatever reference the manual makes is correct.

hsjb - I used Permatex Anti-Seize Lubricant, it comes in a small 1 oz. tube that I’m keeping under the bonnet / tool bag.

I used some P21S wax on thethe wheel bolt threads. They went in smoothly, screwingin with finger tightening and a little wrench/torque wrench work.
Huh? I've never heard of using anything on wheel bolt threads. I've always done my own work on cars and have never had an issue. I don't think I'll use anything.

I always use a light coating of anti-seize. It keeps corrosion and the possibility of a stuck bolt from happening.
Steel bolts threaded into Aluminum hubs require Anti sieze because of the normal corrosion that occurs. It also makes the torque wrench process more accurate.
Interestingly enough, it is not recommended to use anti-sieze compound on spark plugs; yet, that is dissimilar metal. That is becasue there may be some interference in electrical conductivity.
On recipricating aircraft engines,however, like Lycoming & Continental, I was instructed to use anti-sieze on those mating threads. And the Lycoming design was by Porsche!!
I doubt that including a very thin film of anti-sieze will impact the torque on the wheels; however, I would opt to go without it to ensure that the wheels stayed tight. If/when using dissimilar metal botls, they should be periodically (scheduled) for removal, cleaning, inspection, and reinstallation/torque.
The Cayman owners manual calls for the use of anti-seize.
Those of us that are waiting have nothing better to do than read the manual....
ARP molylube -- the same stuff you use on headstuds. It increases the effective rate of torque by 20% so instead of 96 ft lbs (Porsche manual) you can go with 80 ft lbs. It's great stuff, and lasts for a long time.
