Rear Clunk

Rear Clunk
I think something (either a bushing or a shock) may be going on the passenger rear side of the car. When I hit bumps on that side, I get a "thunk" or "whack" sound instead of a dull thump. Any idea what that might be? I've looked everywhere for loose fittings--everything is bolted down tight.

FG2s. I have the Ground Control bushings set to the exact same height, measured with a caliper.
I was thinking about picking up a set of K-Sport coilovers to replace the stock FG2s. Any thoughts? I'm unwilling to spend $2,400 on a set of KW Variant 3's. If the K-Sports are an upgrade over the FG2s, it'd be nice to know. I think their springs aren't as stiff as mine, but they have spherical upper mounts.
Edit: Scratch that--I don't think they have spherical upper mounts. Damn.

If it's negligible I wouldn't pin that as your problem, I just mentioned this because I saw my drivers side rear sists an inch lower than my ps rear. find a bumpy road and drive over some bumps with one rear wheel, and keep the other wheel on flat ground and compare the results after doing so with both sides.

Unless something is loose, or you can see a bad bushing/mount I would definetly say shock.

endlink probably. unless your sway bar bushing is just shot.
tighten up both ends of that endlink good...especially the bottom. Be sure to use an allen wrench on the bolt to hold it while you use a regular wrench or gear wrench. Sometimes they seem tight even when you use a socket. To test, unload the suspension and hit upward on the bar, it should reproduce the noise if that's it..
could be a loose shock mount or other stuff too but try that first. make sure the spring isn't crooked when you lower the car too. sometimes it doesn't sit on that perch right

Found it on Sunday.
Turns out driving-related bumps/vibration had slowly unscrewed the top shock mount nut. Apparently I didn't tighten it down well enough when I applied the Feffman fix.
The tricky part about this one was that the shock nut looked and *felt* tight with the small crescent wrench I could get on it in the car. When I pulled both shocks out and compared them, it was obvious that one of them wasn't torqued all the way down. A couple of turns with a 15mm gear wrench solved that problem.
Everything's nice and quiet now. Thanks, everyone.
