Rick I have all the EPI spring rates if you want them. Primary and secondary.

 

I have heard from customer feedback that the system may work better with several discs removed - try it for yourself .


I have the listed spring rates too , the better way to compare is on the same testing tool . I want to test them for myself , that way I get a good comparison from manufacturer to manufacturer.

 

I will take some disks out and see what happens. I dont have the quiet core because I dont like the way it sounds. It sounds like a leaky exhaust.
