Aluminum Diff Bushing Inserts

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!

Done it. NVH is very subjective.

Having said that, and on my scale of 0 to 10, I sense about a "2" increase at idle and low throttle applications. More throttle than that... exhaust and engine resonances dominate...but I have a lot of metal in the rest of the chassis and driveline mounting points as well.

Absolutely not as bad as, for example, C6 Z06. Installed race engine mounts in one of those and it was nearly unbearable except at nearly WOT... not a street car anymore.
