Do who need to lift it?
I have not done removing my wheels with center locks and I watched numerous videos on youtube. Do you need to lift the wheel off the ground before you unlock the center lock?
I figure you can break it on the ground but I see people the car lifted before they break the center lock.
Which is the right way?
I tried breaking the center lock but its too tight.

The centerlock nut and rim have a mating conical shape. If you loosen the centerlock nut with the wheels on the ground, you risk galling that surface as the wheels shift (tilt) relative to the centerlock nut. That would make the centerlock nut not seat properly on reinstallation. Further loosening could damage the aluminum holes in the rim where the drive pins fit.
I assume you want the car on the ground so that there is less issue with the wheels spinning when you try to break the centerlock. Put the car on jack stands. Engage the parking brake. Turn the car on, push the brake pedal hard, and block it with something. (I've got an extendable rod that I purchased to put into a golf bag so that during transport as luggage, the clubs would not get damaged. I put one end on the brake pedal, the other against the bottom of the seat; move the seat slightly to get maximum brake pressure.) Turn the car off. Now the wheels should be blocked to the point that you can remove the centerlocks without the wheels spinning.

Must be off the ground for both removal and install. If you loosen them while on the ground, you have essentially probably done damage. Follow the Porsche guidelines and let nothing steer you from those directives.

And my worry is when I was trying to remove my right rear wheel, the car is still wiggling a little. So if I try thesame force I am using to unscrew it, it may be more unstable.
I just want to loosen it in the ground then finish it with car lifted.
Im wondering if there is something preventing it from getting loose while in the ground as I cant unlock it. I have a breaker bar and a extra pipe to extend it and still no good.
My breaker bar and pipe has been my go to secret weapon to change tires, but I may end up buying this precision breaker bar if it really wont work. Its $330 which is not cheap.
Any one used something else cheaper to unscrew a center lock?

You can’t loosen it while tires on the ground. Needs to be up. I remove mine all the time and it’s not that difficult. I have the telescoping breaker bar. For the front you need a clamp or a friend to hold the brakes.

I was about to buy a torque multiplier at the store then I saw a 3/4 driver breaker bar 21 in long. It was cheap enough that i tried it and I got it loose.
I was using a 1/2 breaker bar with a pipe initially.
I tried on the ground first, when I felt it was about to give, I lifted the car. I was not really comfortable doing it lifted first, the car is moving when turning the breaker bar.
Now for the torque wrench, it seems the Precision instrument is the the most most effective being it is combo unit.
I dont mind having this extra breaker bar for the other garage/

Im going to drop off my wheel at the dealer to change the tire. Had a hole on the sidewall.
Good thing I signed for the tire and wheel insirance.
Ill ask them why you need to lift it when umscrewing the center lock.

You’ll probably see them doing it correctly. What I have noticed is the use of the paste is very important. Some don’t use enough which makes it difficult to “break” this initial grab. I use the Porsche paste and the protective center tool once the lock is removed. Don’t want to damage the rotors or wheels.

It helps to have a wife who knows how to use the brake pedal AND who does not hate your relationship with your car.
