nice... you should also pick up some chrome, black chrome or powder coated wheel bolts as your rusted ones look... well rusted.
McGard now makes a locking set for Porsche w/ floating collar which I put on my car (in shiny chrome to match my HRE P40s)
See ebay:
item #: 320653592985 for black chrome
or

for more details. Not associated w/ seller, just satisfied buyer.
Good luck
