If you have access to a lathe, motor shims and a brush alignment tool, then save yourself the money and get the normal version instead of the pro.
The factory has shimmed the motor, trued the comm and aligned the brush hoods. The only advantage is they come with a dyno sticker that gives you some idea of how good the motor actually is...
