These are four different stators used in the 245mm converter to alter stall speed and torque multiplication. Note the differences in fin angle and window proportions. Dozens of different stall speeds can be achieved by using the right fin angle on the bowl and the right stator combination. Experience will allow the builder to select the right combination based on the particulars of your car and its intended use.
