What should he do, problem with OPC ?

Thank you for all the replies which have been helpful. He’s decided to take it to B and have them fit a new caliper. In order to preserve the cars integrity and to ensure that he’s able to trade it in to an OPC this is the only way. He’ll endeavor to get one or both to make a contribution to the costs.
One final question, is it possible or likely that a Centre Lock wheel can come loose between services ? If yes then surely there is a need for service inspections between times.
I haven.t heard of C/Ls loosening of their own accord as long as they were properly locked in place last time they were taken off.I have heard of them popping off if some water moisture got trapped in the C/L mechanism, which heats up to steam under very hard track use, with the resulting high pressure.One final question, is it possible or likely that a Centre Lock wheel can come loose between services ?

The torque setting during the 991 build has always been 600nm.
These cannot I repeat cannot come loose if the securing spline is in place.
Many of GT3 owners especially the ones who use and track the cars will have the required equipment to manage wheels.
Picture 1 is not engage correctly although CN is torqued
Picture 2 is torque and anti-rotation engaged properly
Correct procedure as follows
Apply manufactures grease to nut as procedure
With wheels raised off the ground torque centre nut to 600nm
Back centre nut off 60*
Retorque to 600nm still with wheels raised off ground
Check anti rotation in place if not using a 1/2" drive manipulate the anti rotation into the fully extended position.
Now lower wheels to the ground and install dust cap.

Can you explain the difference between thise pics please. As someone who’s never used Centre locks I cannot see any difference between the two!These cannot I repeat cannot come loose if the securing spline is in place.

Centrelocks are a curse imo, an absolutely idiotic thing for a road car.
You make it sound like they are constantly falling off. Never had a single problem with CL in many years of driving many road cars. And all for what? Just for the stupid faux race car look on centrelocks that aren't even threaded properly on 911 road cars! Good for you if you like them though.

The anti rotation lock is the silver bit right in the centre..In the first pic this device is still unlocked as it still hasn't popped out into the splined wheel center..In the second pic this device has popped out and is locked into the spines in the wheel center.Thanks!

Personally speaking I find them an immense irritant as it's a pain in the ass (monster torque wrench, fking around with the aluminium paste and all) whenever one has to change pads, change tyres or worse yet have a puncture. And there's having to replace the bloody things after a certain amount of track mileage plus they corrode rather easily.

Sure I get they can be irritating but I wouldn’t go so far as to call them a curse. And all for what? Just for the stupid faux race car look on centrelocks that aren't even threaded properly on 911 road cars! Good for you if you like them though.
Update today is the the replacement caliper was due to be fitted by OPC B next Thursday, got the dreaded call to say they were not in stock in either Porsche Reading or Porsche Germany and there was no information when they might be in stock.
He’s really upset and disillusioned and has decided to park the car up. I’m sorry for him but he’s not for turning or getting it repaired. I might add we are an almost three hour drive from OPC A and OPC B is a further two hours away.
