This probably doesn't fit into the game of X-wing, but maybe someone has a ship that could benefit.
Thus far all vessels have symmetric maneuver dials. Bank 1 right and Bank 1 left, for instance. Both are also the same color.
It would be cool to see idiosyncrasies creep into the dials for exotic ships where such symmetries are broken.

In WWI planes with rotary engines could sometimes turn 270-degrees in one direction faster than they could go just 90-degrees in the opposite direction. This was due to the incredible mass of revolving metal (i.e. the engine) acting somewhat like a gyroscope.
In this case, perhaps a vessel has a "white" turn to the left but the corresponding turn to the right is "red"...or non-existent.
This is a subtlety that could allow the ship's opponents to more accurately predict where the vessel will be in the future, based on knowledge of the ship type (and it's capabilities).
Like I said, this seems more like a great idea for a "Wings of War" reboot, using the Flight Path system, than something for X-wing as it exists today.
