Porsche 911 GT3 R Technical Manual page 110

Please check the setting (tightening torque) of the wheel gun. Tests have
shown that the centre-lock threads can be damaged if the wheel gun is
incorrectly set. The above mentioned procedure must be strictly adhered
to. A control test must also be carried out to ensure that the required
tightening torque is also achieved (also different wheel guns supplied by a
different manufacturer and specification).
Two different wheel guns are necessary for both vehicle sides. Source of
