Interesting build

Finally was able to get some progress on the FRS (my Nissan Pathfinder has been keeping me busy with a crank but no start condition, plus I replaced the valve covers, and spark plugs).

Got the original rear end cleaned up in preparation to tearing it apart.

What do you have planned for it?

I'm planning on installing a number of parts on the rear subframe:

-Install Weir 4.556 FD (I'm replacing all of the bearing and seals)
-Repack axles w/Redline CV-2, replace boots
-Clean & paint subframe, knuckles, control arms w/VHT epoxy
-Install STI differential mounts
-Install STI subframe bushings
-Install tS subframe stoppers
-Install longer tS subframe bolts
-STI pillowball trailing link set
-MCA Traction Mod II

I plan to make a video of each step of the process.

If anyone here has any Group N bushings for sale, let me know, as I would like to install them since it's going to be completely disassembled.

Can you please share pictures and part numbers for the sti parts? Preparing list for 2026 mods, and my focus is going to be on rear portion of the car to reduce movement on turns with 100tw tires on track.

BTW, I have an extra brand new pair of the STI subframe bushings ST20174AS000 (four are needed). I'd do $60 for the pair.

How hard is to change that? Never changed something in this order

I am not sure, as I haven't tried it. I have a 20 ton hydraulic press and a press sleeve kit. I don't think its too bad but won't know for certain until I actually do it.

There were lots of distractions during the summer, so I didn't get around to disassembling the rear end.

Recently, I purchased a GR86 OEM catback ($100, I'll install it when I swap the updated rear end back in), a brand new BRZ tS shift knob ($148, part number 35022CA100) and a 2018 BRZ factory Carplay radio ($100, part number 86271CA670).

For the radio, seems I'll have to repin one of the wires in the harness to get it to work correctly. According to @Clipdat, the blue and white remote wire had to be moved one slot over on the harness (see attached pic).
