My wife has a 02' Beetle and we just picked up a couple of factory lug bolt covers from the dealer (Her Beetle was missing a couple). They were $1 each. I didn't get a chance to try one on my Boxster, but if they fit, I'll grab another 20 of them.
I ditched the locking lug bolts long ago. If anyone wants to steel stock 97' Boxster rims with worn tires, power to them.
