The irony of this is that Porsche's center locking wheels have been widely panned as an unnecessarily expensive and cumbersome invention. They require a maintenance schedule that is ridiculous and have left some track guys up in the trees from wheels falling off. Removing them requires special tools and procedures for exactly what benefit no one knows. Some even go through the huge expense of converting their $100K cars back to the old five lug.

So to accuse this $300 mod of being unnecessary is funny. I appreciate the handywork by this Asian factory to make a good looking block of industrial design. But at the end of the day if you run into a performance driving-oriented onlooker, it's a bit of belts and suspenders situation.
You'd have to figure out a way of masking the lug holes completely, which I'm fairly certain I've seeen. The whole lug area was cap mated to the CL center cap. Kind of cool I thought.

Porsche did a center lock recall after a few incidents of wheels coming off on the street and at the track including the ring.

Yes you do need a special big-ass wrench and it has to be perfectly torqued otherwise the wheel might come off.

All just for saving a few pounds of unsprung weight (and to restrict you to do any DIY).

But same thing can be said for PCCB... track guys all convert them back to steel rotors and pads.

Here's a satellite image of how they're made.

That picture is from the beginning of the process and really understates the skill and precision that's involved in shaping these beautiful center caps after the metal is digested...
