I just installed aluminum bushings for the cradle and was wondering if anyone has installed the Steeda (or any other brand) aluminum diff bushing inserts? I know NVH is increased but I am reading so many conflicting articles about them. For those of you that track your car what have you done (road coarse)? The car is not an everyday driver so a little NVH is not a big deal. I am just wondering if aluminum is worth it. I would love to hear feedback from those of you that have installed them. Thanks!
