Hi I have a 964 and I am considering buying a members stock calipers to put on my 964. I know I would have to make an adapter. I am wondering if anyone knows the piston sizes in the calipers so I can see if it will work with my master cylinder. The part numbers for the calipers that I was given are.
9973524210b rear
997351421/422 front.
If Nyone has the piston diameters that would be. Huge help

I can't directly answer your question, but the 991.1 service manual may have the answer:
