Steeda "stop the hop" kit

[MustangNoob]

has anyone installed the ultimate handling kit? I have the starter one and I'm thinking to upgrade. I have some concerns for the NVH that the differential bushing insert might add. Anyone having any experience with this kit?

I have the full kit installed. I get some driveline noise transferred under deceleration but that's about it. I actually like that characteristic of it. Makes it feel more racecar. No vibration or harshness though.

I also have the full kit. I really do not hear the noise under deceleration; I do hear some things- not crazy loud, just sounds as if things are working as they should.

I have the subframe support braces and alignment bushings along with jacking rails and haven't gotten any extra noises. I had the same concern with the inserts so skipped them for now.

I have :
. Steeda Mustang IRS Subframe Alignment Kit 555-4438
. Steeda 555-4437 IRS Subframe Bushing Support System
. Steeda IRS subframe support braces 555-5754
. Steeda 555-4137 vertical links with Polyurethane Bushings.

It transformed the handling of car, and absolutely no NVH. Highly recommend it.
