Tuning tip: Shim all the arms to rid the play in them. For upper arm shim set, ZC-S25. Lower front and rear arms shim set, ZC-S30. Also suggested are aluminum spacers. They key is to shim them so there is little to no play, yet does not bind (Stay stuck when arm is lifted). When you have binding issues, your shocks are't able to function correctly. If you have any questions, feel free to ask. We are here to help!
