Need the S8 Brembo callipper's piston size (Refurb kit)

[SilverS8]

Hi. if anyone know the diameter of the pistons or have a spare lying around to take measures from that would be absolutely perfect.

Yes, i can take mine off(and will if nobody has)

Spoke today with the a Porsche spareparts store here and they would provide new pistons and seals if i could get hold of the piston size and a few closeup pics of the callipper. He just delivered new pistons and seals to a Volvo R(something) where the Volvo dealer claimed only new calippers are offered.

Hopefully a refurb kit is in the process.
