Short inside leg body: smaller frame?
Track frames in general are designed for manouverability, not stability or comfort. This does not make them very good commuter bikes, but if you absolutely need a track frame you know what you are getting into. Extra long stem tones down the twitchiness a bit, but also moves the weight distribution towards front wheel.

Another solution would be buying a road frame with horizontal dropouts and not installing a rear brake. This will get you a top tube that is only moderately short related to your body, but would lose some credibility (if it was 2007, this is 2017 and track bikes are old news anyway).
