Default The dreaded centerlocks

Is the design of the new GT3 centerlocks the same as the one so oft criticized on the GT Boards? Never having had them before, I am curious if the tools will be provided for proper torque and if service will be able to be done at my local independent P guy and local tire store. Thoughts?

The new CL's are described as improved from the old design. Someone with access to a GT3 has to take it apart to confirm the "improvement". With the 3D printer technology available today, you would think Porsche could come up with a couple of mechanical mockups to show the improvement without much cost.

Best to buy your own 3/4" torque wrench that will be 4' to 5' long just to be sure!
Not to many tire stores have one laying around.
To be sure they are a PIA!

Indications from Porsche are that the new units are different, improved and stronger. One would hope that whilst 3 years too late, having now identified the shortcomings of the 997.2 system, the issues have been thoroughly addressed to avoid the embarrassment of viral videos on youtube of P cars doing NBR on three wheels. Time will confirm...

As mentioned above, you will require a vvvvvveryyy long breaker bar and a 3/4" torque wrench to do them up. Porsche only supply the socket for the CL bolts with the car. You'll also need an understanding someone to stomp on the brake pedal unless you go the brake depressor pathway... Many threads about these.

The procedure of the existing system is complicated and we don't know the new system yet but if its anything like the original you'll want to be 1000% clear on it correct use and allow only those with experience and full understanding of the system to touch it. I would not let a local tyre store or local mechanic anywhere near it unless they have been trained. A local race shop only if they are familiar and you are confident in their abilities... Two people touch my CLs, me and the motorsport team at my local dealer. Nobody else! They take being **** to a whole new level...

Total pia, you'll need the Porsche breaker bar and/or a torque multiplier.

Great info! Thanks. Its hard for me to believe that P would put this on owners without good reason. Why have they done this when other manufacturers have not?

The 991 may have magical CLs that are much simpler to use, until the design is 4 years old and wheels start falling off.
