Does anyone own a centerlock Torque Wrench?

If you are referring to what I was suggesting, it's not this. What I was describing is taking the racing floor jack lever (basically a very long pipe that everyone has anyway because you need a jack to lift the car) and attaching it to the end of the split-beam torque wrench instead of the torque-sensing handle by just sliding it over. This basically turns the torque wrench into a giant 6-7ft long ratchet with no torque-sensing parts to damage, which is a great breaker bar (no, it will not break the ratchet head at least on the Precision Instruments wrench - that ratchet head can handle it without an issue). I still can lift more than 400lbs, so I do not need to do that, but I've seen many people do it while changing their own wheels at track days.

No, not at all - I was just asking why this wouldn't be referable to hanging off of a 5ft breaker bar in order to loosen the lugs: Just have the breaker bar attached to the lug set to "up loosens the lug" and use the floor jack to apply pressure. That way you wouldn't need a long bar at all. Jack can apply 3 tons of pressure - obviously you would never exert that on the lug as it would loosen long before that... But maybe this is a terrible idea.

You can use them on a Cup car, since there is no locking mechanism. However, those racing CL nuts get pretty quickly destroyed on Cups and are frequently replaced.

I don't know if you bought the stuff yet. But I can tell you that I have heard personally from the owner of Smart auto (they have Audi in our area) that when his Porsche dealership closed he retained 2 of his Porsche techs and they still work for him. Technically he says for tires and easy stuff they could do the work. Could be worth a try.

I think the hub is aluminum and aluminium cracks from impact. My Cayenne manual says not to use an impact wrench when changing wheels as well, and it has no CLs.

I have a Renntorq,Precision,Extra socket,wheel guide and additional 48" breaker bar that isnt long enough if the nut is really tight
What a joke i spent over 3K to be able to remove the wheels.
I love when people say that there no more hassle than a 5 bolt.
The cost to remove the 5 bolt wheels $0
Center lock wheels on a street car are worthless.

I would love to have one for my garage but wouldn't want to count on it for an emergency , low battery?blown circuit board?
Its probably a long shot of a malfunction but why take the chance ,lets not forget its twice the price of the Renntorq 5K vs 2.2K.
The Renntorq is all manual which i prefer in an emergency.
Bottom line is no matter how you take them off their a pain in the ***!

Here's a stupid question. On my 5-lug wheels, I use the breaker bar while the car still on the ground to get the lugs slightly loose before I jack up the car. Same for torquing them down, I tighten them pretty good, then lower the car before I torque down. I am assuming that's not a good idea with centerlocks but can someone perhaps explain why? Is it because the weight of the car will misalign the wheel? It's my first time dealing with centerlocks.

I only do it with car off the ground (requires a second person to press brakes and hold steering wheel, unless you have fancier tools).
Rationale is that you will apply uneven forces to the mating surfaces with car on ground.

Bear in mind that manufacturers recommend torquing wheels to the proper spec even when dealing with 5 lugs,although in that case it's not as critical because the load on the bearing is distributed differently.
