Nissan does not release the numbers. A lot of people were asking about this a while ago when the NISMO suspension first became available and no one could figure it out. To find out you would need someone to take a 3rd party reading from the stock shocks/springs, or submit a formal inquiry to Nissan that in all likelihood would not be answered :P

The oem bars (as per 350EVO) torsional deflection rate on the front sway bar is: 1100 lbs./ in. The OEM rear bar is 380 lbs./in
In comparison, this is how the EVO350 bars measure in LBS.
front bar
soft 1010 lbs/in
Middle 1225 lbs/in
stiff 1460 lbs/in
rear bar
Soft 370 lbs/in
middle 475 lbs/in
stiff 580lbs/in

Those were the numbers for our old stlye rear bar before they went into production. We then switched to a 15/16 size rear sway bar.

Plus be have BJ telling us that they actually use a thicker rear bar then what was used for the specs I posted. Even a 1mm increase will net a noticeable increase in bar stiffness, now we just need BJ to publish the correct spec's for the current rear bar.
