Locking Wheel Lugs

I think GM accessories may have them (I know they have other 18" wheels), and dont worry I dont think anyone will steeal them, there is only like a handful of (types of) cars in the world that have this lug pattern, thats why it'll be so hard to find new aftermarket rims that look really nice for the SS's!

Here ya go:

They are towards the bottom of the page.

I guess I am more worried about the idiots who care nothing of another persons property. makes me want things like locking wheel lugs, locking gas cap, and an alarm or other anti-theft device.
