If you want to know what you are going into. Here are my 2 threads on replacing the suspension bushings with the SPL catalog.

The Complete SPL Front Suspension

The Complete SPL Rear Suspension (Almost)

As for replacing the rear sub-frame bushings. Believe you only have 2 choices. The solid SPL kit which replaces the bushing all together. And the Z1 kit which you install parts into the stock bushing. The Z1 kit is the one you want. It still has some flex in it unlike the SPL bushings.

Do you commute in your car with solid bushings in it? I thought that would be super stiff.

I have taken the Z on a couple of long trips with no issues. Actually, it's not stiff. The stock rubber bushing bind the travel movement. For example, if you remove the front coil-over. With the stock rubber bushings. The spindle will stay put at about mid travel, and it's hard to move up and down. With the SPL bearings. The spindle will fall on it's own weight. You can pick it up and down with no problems. The SPL bearings make the suspension more responsive. They will increase the noise and vibes some what.

Thank you all for the feedback.

I'm unsure how many bushings are on the rear knuckle side and if anyone makes poly replacements. Does this look like a complete list of replaceable bushings?

Front upper control arms inner
Front lower control arms inner
Front sway bar
Front sway bar endlinks
Front upper strut plate
Engine mounts
Tranny mounts
Differential lower and center
Rear subframe bushings
Rear upper control arms
Traction arms forward bushing
Camber arms forward bushing
Rear lower control arm inner
Rear sway bar
Rear sway bar endlink bushings

How many are on the rear knuckle? Do the traction, camber arms and lower control arm have rubber bushings on the knuckle side?

thanks!

There is 4 bushings on each rear knuckle. Traction arm, camber arm, mid link and lower shock. You have to remove the knuckle to replace the bushings. The mid link, traction and camber arms have no bushings on the side that mounts to the knuckle. They mount to the bushings in the knuckle.

Upgraded Rear Knuckle Bushings for 370Z and G37 | SPL Parts

There is no strut plate.

Chances are that you will have to drop the sub-frame to get to the rear upper arms. I haven't replaced those yet. That's an after Christmas project.

Rusty,

Thanks, man. I appreciate the replies and info. When I get all of this together I'll post the rebuild.

I thought for sure there was an upper strut plate with the studs that go through the strut tower? Am I getting the nomenclature wrong?

Did I get this right?

What you are seeing, is the upper mounting bracket for the coilover.
