There seems to be no instructions on it from fall line

I would follow the instructions from other vendors like SPL or just email fall line directly.

SPL calls for 74 ft lbs.

Millway sells them, here's the link:

Nice. Any noticeable improvement in feel with these?

This.

There was not one single piece of paper in any of the Fall Line boxes, let alone instructions of any kind.

The inner camber bushing in theory should help with coilover rebound responsiveness.

I will do this bushing once I do the diff bushings and rear sway bar.

I wonder how much NVH you get with that, though 🤔

Based on my past experience, there should be no additional NVH. It will just eliminate any squishy behavior in terms of damping and rebound and should make the rear shock work more effectively.

The only mod that creates a lot of NVH is when you go solid aluminum diff bushings. However it is only noise and not vibration or harshness.

Another mod with high NVH is a lightweight flywheel.
