FB RX-7 Swaybar Question
 

Does anyone know what the pound per square rating inch (LBS PER INCH) is for the aftermarket 1 Gen RX-7 (Racing Beat or Suspension Technique) swaybar is ?
Only asking as I have a Speedway Engineering Front Bar (1.25 Hollow Splined 37.5" with 12" arms) Rated at 411 Lbs per inch and want to replicate or get close to the recommended Jim Susko GForce Engineering recommended rate.
My coil spring rates are Front 300 and Rear 150.

Please do not send me the formula as I do not have the RB or ST bar which to conduct the calculations.
