HP and Torque relates to the engine performance, what happens later down the drive train is a totaly different story.

those "little" 0.1-0.15 differences in final ratio do make a difference, maybe not day and night, but still. if the car is a non tow (sport) then it makes a sense to put 4.10 instead of 4.3
