Idk if this is any help but to chime in on the Whiteline. I actually bought the Whiteline Diff bushing set and my buddy bought the Energy Diff Bushing for his G. The whiteline feels more solid imo. And yes, the ES means you have to reuse the steel sleeve. That was a big NOPE in my book.

well i just ordered the whiteline bushing(ebay). i guess i put some kind of post showing the wear and tear as i put a lot of miles on my Z.
the spl bearing dosent make sense to me. the arm is supposed to go up and down and rotate with the steering. but since its a free moving bearing it also allows the arm to twist freely with no resistance giving you that infamous clunking sound. side note, i dont know if any of you worked on a 370z front suspension, but the lower a arm they use is a much better design.

Ya the ES diff bushing reuses the stock sleeve and that is the main issue. It doesn't use a lock washer either so it's only a matter of time until it loosens up and allows the bushing to push out. I was lucky ii didnt lose my whole rear end. Spl solid is the only way to go if you drag race.
As for the compression bushing it just doesn't fit well. Just putting the car on a lift crushes the **** out of the lower half. Add hard launching to that and you have the pic I posted.
Luckily I found cheap oem compression bushings. If I can get another 50k mi I am happy.

The diff cover survived and just had to out a new bolt in.
And the spl kit comes with a lock washer. Who would have thunk it?

The steel sleeve doesn't back out, the bushing does. My bushing ended up on the track and the steel sleeve banging around in the subframe and bent. Luckily

^^ yes mine is the same. I've chaulked it up to the rear nut loosening itself up after a dozen or so hard launches on drag slicks. Once the nut gets loose from the diff torquing and twisting, the sleeve starts pushing the bushing out a little with every launch. Eventually, you have a broken/missing bushing and if you're like me you also have a bent stud and/or broken diff cover.
For those of you running the ES diff bushing, just make sure the nut holding onto the sleeve stays extra tight (e.g. install a lockwasher!) and that the bushing isn't slowly pushing itself out the rear.
Note that the SPL kit comes with a lock washer, and on top of that the stud and bold holds the bushing in so there's no way it can work it self out and no need to re-use the OEM sleeve.

So, yea I admit that my diff and compression rod sees far more abuse than the typical. I guess some, maybe even most people won't have issues.
ironic part is that the OEM bushings lasted over 50k miles 100 passes like this. And they are actually cheaper LOL...

ES makes awesome products but their compression arm bushings are simply not a thought out product. The SPL spherical bearings are the only solution for lowered Zs, any rubber bushing will eventually fail.
The rear diff mount is the same story, I saw the install instructions about reusing the oem steel sleeve and said no way.
ES answers for the remainder of the car's rubber mounts are great, I've replaced 3 different cars entire bushing sets, including my Z, and have had zero issues.

if your a guy that requires silent or needs to abide by SCCA rules etc, then your best option otherwise at the compression rod location is the Whiteline new compression rod bushing...
its tapered ends are a much more thought out design over engery suspensions hunks of poly on each end.

I already have SPL solid on the diff but I don't want solid anywhere on the front suspension for a couple of reasons. I'm being forced back to stock compression rod bushing for the time being due to frustration/waiting games on the whiteline product...

i have been running the full front ES bushing kit in black for around 8 months now. I recommend getting the OEM bushings because these bushings increase NVH with no added performance compared to my old worn out bushings...
