Affordable Front Sway Bar Stiffness
 

I've done some searching but can't find any definitive rates. I found a lot of xx% stiffer but stiffer compared to what year S2000 bar (they change every 2-3 model years)?

I'd like the stiffness rate or at least which bar is the stiffest from the following:

Eibach
Whiteline
Cusco adj and non-adj

Or any other affordable bar. Thanks.

(Copy and pasted from another post)

S2000 Eibach Sway Bar rates:

Rear: 29mm Adjustable (HOLLOW)
Pos.1 - 90 N/mm (515lbs/in)

Thanks yeah I believe I've seen that. I have a 2000my and if I get an eibach bar it would only be as stiff as my oem rear bar. I'm looking for something a lot stiffer but affordable. Anyone got specs on the other cusco or whiteline?

the whiteline is about halfway between OEM and the saner bar on soft its decently stiffer
I think its 28mm solid steel

Whats your budget?

I'd say less 200. Whiteline seems like a good one so far. 187 shipped on ebay too. It's actually 30mm but yeah solid nonadjustable.

Get a AP2 rear. I am running a AP2 rear with a Eibach front. It is money!

Did you decide on which bar to get? I'm in the same boat.

Saner Front
OEM SWAY BAR 295.5 LBS
SOFT SETTING 566.0 LBS
CENTER SETTING 644.0 LBS
STIFF SETTING 739.3 LBS

Yeah I know what the Saner rates are but its not even available anymore and its not exactly affordable.

Oh, I'm probably going to go with the whiteline bar.
