j/k!
I know I will sound stupid for asking this, but what do you mean when you ask whether or not it will affect the suspention? Do you mean like, will it add any additional strain to other suspention parts that will result in accelerated wear? If that's what you mean, then the bar will won't cause any harm. If you meant to ask whether it will have an effect on the suspentions handling, then the aswere is that it will reduce side roll which will yeild quicker steering response when making directional changes from side to side. Hope I answered your question with one of these two answeres.
