I have now had my new cupwheels balanced again and it seems that the first balancing wasn't in order due to a faulty balancing machine. Also I have replaced my old non original locking wheel nuts with original Porsche items (non original ones were quite heavy). All this has helped A LOT on the steering wheel wobble. Unfortunately it's not completely gone. It still vibrates a bit at 100 to 140 km/h (worst at 120/130).

Therefore I tried the wheels on another 911 and boy am I glad I did. No shaking in the steering wheel! So it means that my car is not in order. Only now I need to find out where. I asked my Porsche workshop if it could be the wheel bearings, but they answered no. It could be the car's wheel hubs although they considered that unlikely.

So now I'm open to suggestions. What else can it be that causes my steering wheel to vibrate? I will soon have a 4 wheel alignment peformed to make sure that everything is correcly adjusted. Do you think that will help?

At least now I know that the wheels can in fact function properly. Instead I have a new problem....

Please let me know what you think - I prefer not to spend a fortune in labor on fault searching.
