Agreed, no need to have any.

 

So, is there a middle ground between Porsche and Tikore? The silver Porsche ones are dry/chalky/worn looking and the Tikores cost a fortune. I actually need bolts for the front wheels and nuts for the rears due to the TechArt spacers. It would be nice to find a solution for this.

 

Or you could do what the owner's manual says and apply Optimoly (an anti-sieze) - never understood why Porsche says use anti-sieze but many knowledgeable folks say don't use it. Are the recommended torque specs adjusted for use of the anti-sieze?

 

As others have pointed out make sure the bolts match the wheels. If they are OE wheels then the original oe bolts will work. If they are after market wheels you have to verify what style (conical or rounded) bolts will work.

I bought a set of aftermarket wheels/tires for my Cayenne, got them balnaced and they vibrated. Had them road forced balanced, still had the shimmy. Got a new set of tires from Hankook, still had a shimmy. Finally called the wheel company and they asked what bolts I was using, OE I replied, well there is the problem, you need new correct bolts. Needless to say, scratched new wheels from putting on and taking off two sets of tires, ridiculous amounts of money on 2 balance jobs only to realize it was the bolts all along.
The wheels and tires balanced perfectly but once mounted on the car at highway speeds is when it becomes evident that bolts not perfectly matched to the wheels will not work.

 

For my 997.1 C2, the recommended tightening torque of130 Nm/96 ftlb is for bolts with anti-sieze applied. With anti-sieze and at 96 ftlb, the bolt imparts the proper amount of pressure between the wheel and the hub. The anti-sieze reduces the friction between the bolt threads and the hub threads and allows the bolt to turn more before reaching 96 ftlb of torgue. Without anti-sieze, the bolts won't have turned enough when 96 ftlb is reached and there will be less pressure between the wheel and the hub. So, without anti-sieze, the bolts should be tightened beyond 96 ftlb.

Re-using factory bolts, spent $17 on gloss black caps, I'll post pics next week after mounted, thanks guys!

 

Keep your speed under 150 - those caps have been known to come off

 

Don't have my manual handy but does is say to apply to the threads or the wheel hubs ? Applying to the wheel hubs, where the wheel joins the rotor hat, eliminates the wheels sticking to the disk hat and eases removal. I apply very thin coat to the back of the wheel where the bolt seats touch the disk. Works like a charm.

 

Lug bolts.
