I have a set of 510's. I know a lot of Evo guys run FA so hoping to get some help here as all my other sources have yet to. On one of my front coilovers the adjustment knob doesn't click. It moves freely with the same resistance as the other three from soft to hard but you can't feel the indents or hear the click. I emailed FA but haven't heard back from them yet. There was another post of a guy having the same issue a few years ago, but who would have guessed that was left an open ended thread with no resolution. Thanks in advance.

 

Call Terry or the other tech at FA in the morning

Report back the details please. I run the 510's as well
