Just putting together my calliper overhaul shopping list, and it seems there are (at least) two different types. Looking up the Amayama parts catalogues, I got a different part number for the overall rear calliper between '95 (my previous NSX) and '93 (my current NSX). Did the callipers change with the upgrade to bigger wheels? If they did, do we know whether the pistons/seals/etc also changed?

To add to the confusion, I am working on a different set of callipers (unknown age) and my car which is some miles away may have had a calliper change in the last, so some compatibility info would be helpful.

Also: Biggred tell me they cannot source NSX calliper pistons, so they have taken the NSX off of the online ordering system.
