Hi Christian, When I got my car, all six struts were shot, so I got a set from PJ Grady. As you may be aware, the original struts were effectively just springs. The replacements from Rob (and I believe every other service facility) have a "brake" in the last inch of travel meaning that the door is slowed down. This means you can feel free to torque up the torsion bar such that the door opens in cold weather, and not worry about it flying off its hinges in the summer :-) It was our first torsion bar experience (quite comical at the time), and my drivers' door still doesn't go up properly, but the passenger door is perfect. Strangely, one notch on the bar made the difference between a real half-assed attempt at opening, and a very keen, rapid movement. It was about 5 degrees C that day.
