It takes up to 90 days to get a speed racking horse and keep them sound so do not skip on conditioning.
Take your time and her's in order to build those muscles for more speed. In time and patience you will have a nice speed racker.
I would like to add: when you feel her break gait, transition down by using half halts. Let those hind legs catch up to the front legs:)
FYI; any bit with shanks and broken mouth piece is still a shank/leverage bit :)
You do NOT need any special bits, shoes or etc in order to get this horse to speed rack or gait, just patience and training.
