Well, we will finally get a chance today to install the Z1 rear differential bushing, larger capacity Z1 differential cover with cooling fins, and flush the differential fluid with better Redline fluid. Fingers crossed that everything goes smoothly. I will report back after the install.
I also picked up some exhaust wrap to use near the differential to hopefully reduce the heat enough so I do not melt my abs sensors again. I believe I can re-use the clips for the exhaust wrap so I plan to just use it during a track day so as not to trap moisture inside and rust out the exhaust prematurely.

The installation went pretty much as planned. I had help from one of my technicians to get out the rear subframe bushing. We cut the bushing and drained it like most people, but then he got creative and used a torch to cut the outer race to get it out. Nice work on his part as he did not even mark the subframe. (He did not want to saw it out and damage the subframe)
I had the bushing packed in ice for a few days to try to shrink it to make it easier to get in. I think that worked as the install was pretty easy with a hammer and some grease. We did not even use the tool from Autozone at all because the drive spline was too big to use on the metal bushing insert. Fortunately, we had a similar tool for a Mitsubishi that we could use. Everything else was pretty easy.
I do not really notice any difference with the rear subframe bushing. I noticed a very slight difference with the bushings in front of the differential. I will try to pay more attention now. I would say this is good preventative maintenance, but wait until you actually need the parts or have the differential out for something else as there is really no performance benefit.

Good for you on the main diff bushing, 4DRZ. Not an easy job at all.
I know you got the finned diff cover for cooling, but it sure looks impressive. Can the cars behind you see it?

The idea actually made me think about my favorite Ferrari and arguably the most beautiful, the 288 GTO, that has the back of the transmission poking out the rear to similar effect.

I suspect that with the Z1 transmission mount, this doesn't make as much of a difference as those of us with the stock transmission mount.

Personally, for the first few days after the Whiteline pieces were installed, I had a distinct impression the car was more tight on the shifts and in low-speed, quick maneuvers.
