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.
