Sway Bar Diameters

myotorsports

Been having a difficult time deciding on sway bars like me? Here is a chart to compare brands, diameters, and adjust-ability. Just data compiled from marketing info. List is sorted by size of front bar, then rear bar, then adjustment points.
I know some of you rocket scientists will bemoan tube diameter, but hey this is for reference and comparison only...
Updated...


Took a look at the other chart and found the original posting- Autocrossing + Surprise Visitor it did not mention how the inside diameter (which determines tube wall thickness) was "guessed". I assumed that the stock and Stillen bars had been measured, so I took a look at common chrome moly tubing wall thicknesses compared to the stock and Stillen figures and made calculations based upon the common tube sizes for the others. Also, I'm not sure what the mm^4 figures indicate, unless each bars length was considered for a volume comparison. This and the other chart really compare tubing area as opposed to spring rate increase over stock. But it does provide a comparison of sorts.

Thank You.

It has been stickied.

Just to repeat a little of what's been discussed in various other swaybar threads, the general consensus seems for track use seems to be that (assuming your tire/suspension/alignment setup is both aggressive and sanely configured/balanced) you want a very stiff front bar and a pretty weak rear. My own experiences seem to back this up running the Hotchkis setup. Since the front on those isn't adjustable, I adjust the bias with the 3-way in the rear.

When I had good coilovers and a bit of drop, but no front upper control arms to kick out the front camber to a reasonable level, I was losing front grip (burning up just the outside half of the tire) and found I had to set the Hotchkis rear to its stiffest just to break the rear tires easier and prevent understeer at the limit. Once I fixed my front camber, the car felt best with the rear set back at the softest setting, and feels like it would be even better if I could make it even softer. In the wet, I absolutely have to have the Hotchkis rear at the softest setting or the rear end goes nuts on corner exits (for now, I should probably consider just disconnecting the endlinks on wet days).

From the easy commercial options listed, my thinking now is Hotchkis in front and Whiteline in the rear would be a good bet. I may swap my rear out over the winter and try that.

This topic has been discussed ad nauseam. Here is a better list from a previous thread.

Is there any downside to super stiff front for a DD? I see a lot of people go with Hotchkis but they aren't adjustable.

The downside is a harsher ride on the street. As each person is different I can't say what level of harshness is too much for someone else. fwiw I have the Eibach bars, front and rear, and don't find it to be too harsh on the street.

The only real issue with the Hotchkis bars is that you can't buy just the front bar. Their rear bar is way too stiff to be useful so you end up buying the pair of bars just to throw the rear away.

I tracked with both the Hotchkis bars installed. Guess what. I'm installing the stock bar back on the rear. The rear is/was a little loose. Lost the balance on the Z. On the street. I didn't find the ride any harsher.

Wondering if you had the 345 rear tires when it felt lose on the rear

Rusty

On the track, some what with the 345's. Depending on how much heat was in the tires, and how hard I was pushing it. With the 325's. It was looser.

I see many people going for Hotchkis here, and only for front.
However, while doing some search, I found some are using Eibach, like you.
Question here: is your car for track or DD or both? and how your setup please?

Thanks and regards,
NASM

Mine is an almost dedicated autox car. Also, I don't run the Eibach bars anymore. I'm running the Hotchkis front bar now with no rear bar. Honestly, if there was a stiffer front bar I'd probably go with that.

Thanks for the reply Gomer. Appreciated.
Now, I now the Hotchkis is the answer and to go for.

The Hotchkis Suspension front sway bar has done wonders for my Z! I noticed the improved turn in response and handling felt more balanced. The right amount of roll stiffness helps. Also there are other brand sway bars that work well on the 370Z.
