This key only fits Porsche / Audi Q7 / Touareg converted eyelets. Ball landing radius 14mm (fits all 5x130 wheels). The locking bolt quality is ok and the key is better (so less worries about breaking threads when removing/installing). The cap is 22mm and the key is 19mm. The inconvenience of two outlets knocks one star off. Review after one year of installation and three disassemblies (torque 133 lb-ft), shock absorber was not used.
