Your observations are valid.... but not everyone has the physical capabilities you have.... and that is no slight.
You may be over simplifying the physical requirements, or just not conscious that others have different physical limitations.
What is easy for you is not necessarily easy for others, I think I am in the five slug camp.

someone will come out with five lugs.
the CL is a fk'g disaster.
or maybe we convert to cup car center lock.....
CGT, 40min chg wheels, you would miss your session if you had to do that then get into race suit, hook up cool suit, fill box with ice etc. it takes me 15 min to change all wheels and that's too long... i need air jacks.

At the end of the day, you're right, some will not have a trailer full of stuff and I've had some practice. For the true spirit of the 911 -- to drive to the track, win the race and drive home -- the centerlock adds yet another question of "sure this is better but is it an improvement?" with each new 911 "feature."
By the way, there is a tool that depresses the brake pedal for wheel alignment tasks -- it's a sort of ratchet expanding rod that braces against the seat or steering wheel and forces the brake pedal down ... I'm guess this will be the next gadget I'll need to remember to brinng to the track from now on.

There is exactly the same torque applied to the nut, so the wheel will rotate. But, if the torque reaction arm of the multiplier is secured by the spokes of the wheels (as with the Carrera GT) then all forces negate. Thus natures balances itself.

Question...
Why would you have to have the car in the air to torque the wheels, provided that you had somebody or a large dumbbell, or that steering wheel brake thingie ?
Can't you torque the wheels with the brakes on while the car is on the ground ?
Will torqueing the wheels to 444 ft lbs.....could it possibly damage the ceter lock ?
So 349 ft lbs is ok for the street and not the track ? (how about autocross...where speeds are below 85mph and generally much slower.
What if I don't use grease ? Will the wheels fall apart ?
I bet they had a situation where the wheels weren't properly torqued in a race type setting and they came off.
So 444 for the track, but at 349 for street...it's ok if the wheels come off the car ? WTF ?

I was thinking about making or acquiring a device like this. If you get one, please do let us know how well it works out... that is, if torquing, swapping, and breaking centerlock wheels can truly be a somewhat painless one-man job with the new torque specs required for track use.
