Grant:

I think this was a big mistake for Porsche to introduce CL for its road cars.  One of the biggest issues is that it's no longer possible for one person to change his own wheels.  Porsche recommends that the car be off the ground when tightening the nut now and that is only possible for the front wheel if someone is inside the car pressing the brake pedal while another person turns the nut.  5-lug may be slightly heavier, but it is far more practical.

 Correct. And that is why many people who track their 911 do not take this option .

Anyway, it makes it also nearly impossible to do a wheel change yourself, as you need the proper tool
