Any body with th fa500 have a problem with adjusting the entenders in the rear. I noticed I can't get a feel for the clicks. And now it's extremely difficult to turn. Any help or advice is apreciated

 

It the extender binding? In other words was it a straight shot from the the top of the shock to the hole? When my holes for the extenders was off I had this problem and I had to enlarge the holes. That aside I have noticed it needs almost a safe-cracker's touch to feel the clicks. I took out my back seat, waited for it to be dead quite, and then adjusted mine by feel and listening for the clicks just for peace of mind.

Doubt it will help much, but wanted to chime in with my experience with them.

 

Anyone install an extender on a Coupe?

It looks to me like the shock mount is directly beneath the rear window, no room for an extender and likely possible when the drill cuts through.
