The page in the Internals Reference doesn't list all the properties that the grob would support, only those for which it has a specific default. You have to explore the interfaces to find other interesting properties that you can tweak. In this case, click "Item" ("This object is of class Item"). You'll find extra-spacing-width in the item-interface. Best, Jean
