The rjm pedal is not something that is needed, just like any other aftermarket parts. The 370z is perfectly fine from factory, nothing aftermarket is needed. We add aftermarket parts to enhance and improve stock parts. The spring and pedal are completely different. Comparing them is like comparing apples to oranges. The rjm pedal will improve clutch function, doesn't matter if it's stock or aftermarket clutches. There is no reason to attribute horsepower levels to the need for this pedal. If you want to shift easier and have total control of the clutch, you should get the pedal.
