Could anybody help me out with the % stiffness Progress Rear Sway Bar provide at different settings over stock? I've been trying to look all over but can't seem to find the numbers. Does Progress have their own website?

 

i can answer the second question:
http://www.progressauto.com/

there's no numbers there though.. but a phone call or email might help.

 

Thanks for the information. If I find out I'll let you know.

 

They said they have only done testing on the 2 hole adjustable design and gave me estimates for the 3 hole adjustable. This leads me to believe that they haven't done specific testing for our car. Either way, he gave me numbers of 120%, 150%, and 180% stiffer than stock.

 

hmm.. good info to know!

yeah... those progress guys get really, really busy... but even so, i know their products are very much better than stock!
