Here's a good DIY technical article from Pelican Parts that gives step-by-step instructions for how to access and remove the engine mount from the Boxster/Cayman. The inserts slide into the OEM engine mount from either side - it's easier to install them with the engine carrier unbolted from the block, but you may have enough clearance to insert them with the carrier still bolted to the block.What is the installation procedure? Just reach down in there and insert them? Can the mounts be accessed easily enough to do that? Or does a bunch of stuff (including the mounts) have to be removed first?
