Because of the many turns in the Lancair suggested rudder guide placement scheme, there is a great deal of friction -- even more so if the optional co-pilot side rudder pedals are installed.  For some people, this is a benefit because the in-flight friction is great enough to keep the rudder trimmed in cruise flight (it stays where you put it).  Some of us ran the cable guides as straight as possible, such as along the elevator pushrod tunnel walls with the crossover in the tunnel, exiting just aft of the nose gear well.  This results in a very low friction system requiring rudder trim, usually a bendable tab to optimize cruise trim.

Leading Edge Air Foils (LEAF) has an online catalog

and is a supplier of ultralight kits and components.  They have an inexpensive device which seals the cable and guide at one end and provides a port to inject lubricant down the guide to the open end.  I believe they also have a recommended lubricant for SS cables.
