Paraphrased from an article in Mopar Performance News: “The Koni rebound rate has a 100% adjustment from soft to hard, and it straddles the ACR Arvin strut setting. In compression, the rates were changed to respond to different piston speeds. At slow and medium piston speeds (body roll, etc.), the valving is stiffer than the Arvin ACR strut. At fast piston speeds (impact from bumps), the Koni valving is softer than the Arvin ACR valving. ” – Erich Heuschele 1.4.7.
