I am having the same problem as Kaine. I am attempting to use the aluminium FFR shifter with the long cables on a 5 speed. Shifting into 3rd and 4th is possible but it does not go very smoothly. Shifting into 5th or Reverse is impossible from the shifter. From the back of transmission shifting through the gears is not a problem. At this point I don't think I have any other choice but to consider the MR2 option or Wayne's option. Very disappointed with the FFR setup.
