For those who have installed spacers- what did do you for a wheel lock, if anything? What is the effect on handling?
How did you decide how big of a spacer to go with? I am contemplating 7mm all around, or perhaps a little larger in the back. My concern is throwing off the balance of the car. Porsche offers a 5 mm spacer with wheel locks, but that size is not really even noticeable is it? (except to you, Arling)

 

I have 7mm rear spacers and simply use the Cayenne bolts which are the right length for the rear. I still need to order 2 Cayenne wheel locks though. If anyone has a source for these please PM me.
