With 550 miles on my 992-911 Turbo S. My right rear tire went instantly flat on I75 in Florida. No warning it was going flat. I called a flat bed to take the car and me home. While I was waiting I attempted to install the front Tow Bar, unsuccessful for about 5 minutes. Turning it to the right it would not catch the threads WTF. Then something in my head said try turning the bar to the left. Well, that worked. Never would guessed the tow was a left hand thread. Keep that in the back of your mind if you ever need to install your tow bars.
