Anyone have a recommendation for anti-theft wheelnuts? Horrified to discover that my car doesn't have any!!! Are F-car wheelnuts special in any way or would Porsche ones (for example) be okay? I shudder to think how much a new set of wheels on a 456 would be???? Maybe I could use the experience to get a nice aftermarket set of chrome rims though... Mmmm... Ahem... Cheers for any advice, Dan
