Opinions Desired for Energy Suspension Rear Swaybar Bushing Sizes

I'm looking at my options

Current Swaybar on car is 0.94" or 23.876mm
Current Poly bushing on car is 24mm => Energy Suspension 9.5160 (or 95160G)
Therefore, gap is 0.124mm oversized

If we go with the 0.91" (or 23.114mm) swaybar to see if that will help handling, we have three options:
1) Run with the stock rubber bushings. Probably 100K mi on them.
2) Use the current 24mm Poly bushing (0.886mm too large)
3) Buy a 23nmm Poly bushing and sand it out a bit (.114mm too small) => Energy Suspension 9.5159 (or 95159G)

I'm guessing the right answer is #3 but i'd like your opinions here.

I just pulled the old swaybar off the car and tried the 24mm bushings on the 23.114mm bar (0.91"). The 0.886mm gap allows for too much lateral movement (rocking) compared to even the worn OEM Cleavite bushing that was on the 0.91" bar to begin with (well used).

Option #3 -- buy a set of Energy Suspension 95159G bushings is the way to go.

Seems like some bars are hollow while others are not. Not sure about this case though. You know for sure when you pick them up lol

Depends on the help you want.

Let's say you have a neutrallying handling car, but it rolls more than you like.

So you put a front anti-sway bar on it to help hold the front down.

That, by itself, will create understeer. That is, S4Gunn goes into a corner, and it wants to go straight instead.

So you beef up the rear anti-sway bar.

Oops. You went too far, now it OVERSTEERS - S4Gunn goes into the corner, turns the wheel to turn 90*, the car goes through 115* as the tail end swings out.

What S4Gunn is probably wanting is to tune for a small bit of understeer; or it's currently oversteering.

Sometimes, more is not better.

Sometimes, less is better. Depends on what you're doing and how you're driving.

Also, the stiffness of the shocks will affect the ideal sway bar stiffness (which is, all else the same, related to the size).
