Looks like you don't need any re-boring or replacement of pistons, just some boots. Thats easy, just buy some boots and put them on with a hook and pick. You could find Porsche parts but I'm sure this is not the only car to use these brakes (hint).

I needed to replace brake fluid anyways (had a close call with old fluid!). So that precipitated into a caliper rebuild just to be sure I covered all the bases. Try that 1st before you replace calipers etc. Good luck!
Thank you both for a good advice.
I'll try to avoid the re-boring these as well (some 30 years ago have done it and it was not so good result as I hoped for...).
Current plan is to paint the calipers, flush the brake fluid, swap the new seals and boots during this upcoming winter the latest.
