So my rear diff bushing went to **** and I'm looking to replace them. Has anyone used the Z1 bushing that can chime in and give any pro/cons reviews? Any NVH? Heard good/bad stuff about Whitelines but Z1 is little cheaper and easier to install according to them. Thanks!

I have yet to install my Whitelines. Interested to see what other people have to say now that most have had time to get some miles on them.

I’m in the same boat. In for some feedback on the Z1 rear diff bushings.

Member 4DRZ told me the Z1 bushing is holding up fine. Been on his car for 3-4 years now. I also placed an order for them plus their diff covers so I'll chime in when I'm done messing around with it.

I haven't had the Z1 bushing in there long enough to report on longevity. I did subframe bushings at the same time, so I can't make an NVH report solely on the rear bushing.

What a pita!! Never doing that again! Anyways, a little update with the bushing... well nothing noticeable. No NVH so that's good. Not sure if it's in my head but I guess it does feel a little solid in the rear? And for the peace of mind of course but if you're installing the Z1 cover, make sure the bushing is pushed all the way in, maybe even passed the back of the subframe a little bit because there's really no room to bolt the diff back up. I learned it the hard way and tried to rush the job.. ended up striping both the front diff bolts because it didn't lined up right.
