I realize this is counter to what most are looking for, but I'd be interested in an adjustable front bar that can be set SOFTER than the stock bar. This would be for track use. I am running 500-front/650-rear springs on 3-way JRZs, no rear bar plus a wing, and I find that the car pushes slightly with the stock '03 front bar. A non-adjustable softer bar would work also if it happens to be the right stiffness, though it would be nice to have an adjustable range from softer to stiffer than stock in case I try other combinations of springs. Anyone know of a softer front bar?

 

I doubt you'll have any luck finding a softer bar since the market for them is so small. Have you considered milling down the center section of your stock bar?

Mugen has a 25.4mm front bar. King shows it here (near the bottom):

You could probably buy a swaybar from Small Fortune Racing (Bill Gendron) and then buy a stepped down center bar from Speedway Engineering. Bill's standard S2k sway bar arms have 1 1/4" spline, but if you work with him, he probably could make the arms starting with 1" spline, then you wouldn't need such a radical stepped down center bar. In fact, if you tell Bill exactly what you're looking for, he would probably get the center tube you need to acheive the sway bar rate you are looking for. In my past experience he has been quite flexible.

Speedway will make nearly any center bar you like to your custom dimensions. So, you should be able to get any spring rate you want. You may end up having a collection of center bars to cover the range you are looking for, however.

Thanks for all the information. If I do anything I'll report back, but will probably first get some more experience on different tracks and with different damper + wing settings.

 

Isn't the '00-'01 MY OE FSB slightly smaller (like 2mm.)?

 

I'm pretty sure it's the other way around -- that the '02 got stiffer springs but softer sway bars.

The 00-01 swaybars were the stiffest OEM ones.

 

Why not just put your rear sway bar back on? That would solve your pushing problems...

Removing the rear bar alleviates inside rear wheel spin...huge improvement as the bar lifts the inside wheel, but need stiffer springs to retain roll stiffness (which I have done). The other solution is to go up to maybe 700+ lb rear springs, but this would be making it near uncomfortable for the street, and I am not sure if this wouldn't hurt handling without tires with stiffer sidewalls like slicks.
