NST Lightweight pulley

[Zero2Endless]

If a lightweight pulley is installed onto an engine...being lighter will it throw off the harmonic balance of the engine...resulting in reduced life of the engine?

from what I have read, the NST pulley reduces rotating mass but does not provide a balancing function for the engine. I believe it has other things that dampen the rotating assembly.

i,ll be straight honest man i have the pulley...for a while since sema
i really havnt noticed one change neither for good or for bad...i just really like it because the way it looks on the suspension view with all the other components...i am not the best gas mileage wizard so i cant tell a difference
now i dont know if this may be because the pulley or my brake kit but when i make a sudden stop the cube reacts slow on the engine noise almost like the braking was to quick so i hear a bit of disbalancing on the engine noise..i am not sure exactly what does that means but same time im not so sure if its because the pulley been so light or because the brake kit is so huge lol!

we need more versa opinions with the pulley on
