Installing wheel spacers....caution
 

I was changing to longer studs and adding wheel spacers and noticed something to be careful of.

The new (Porsche OEM) studs have a slightly larger head and will not sit down on the hub surface properly. If you look at the picture, you can see the lip from the old studs. The surface should be flat all the way across with no lip. I spot faced them in the mill to remedy the situation.
