Rep Power: 0

I have wonder if putting a set of new pulleys in my car will make a difference.
got some friends that have them but they tell me that it doesnt really make a difference but others say that it does, i need a somebody to tell me the straight story about the pulleys, also about the grounding kid, i've been told that it would give me a bit of hourse power if a change the kid.

thanks for the advice
