IMPORTANT UPDATE!

[Yoshi]

This past weekend I killed my passenger's side rear coilover... How? Hitting a pothole. Shit u not. Granted it was a 4" deep, 8" diameter pothole, but still.

Driving my friend home, the roads where he is are Extra crappy. I couldn't see the hole in the dark and BAM! Fortunately he lived 30 feet from the pothole, so we limped to his place to check the damage... the shock was making a terrible metal-on-metal banging noise. Upon inspection, and jumping up and down in the trunk, we noticed that the shock shaftwas moving up and down INSIDE of the mount assembly. Very Bad. Without proper tools, I hobbled my ride home, and jacked it up in the garage.

After removing and dissasembling the shock, I noticed the mounting washer (a large 2" diameter steel washer that basically takes all the force from the ground, so either the washer bends/breaks or the shock compresses.

Aparently the score is Shock 1, washer 0.

the washer was bent into a cone shape, and the shaft went straight through it. So i flattened the washer again in a vice and knew I needed something to strengthen the washer.

It so happens that the washer that holds the bottom mount of the shock on the hub carrier is the PERFECT size! it's also thicker and bevelled, much stronger. SO I doubled up the washers, and put silicon sealant tween them so they wouldn't chatter together under load, put it all back and TA DA! all better.
I check the other side, and it was just starting to cone, so I did the proceedure on that side as well. (yes, I got washers to replace the shock mount ones)

Moral: It seems maybe the GC's are not as strong as they should be, but you can re-enforce the setup with stock parts <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=''> Owners of AGX and Ground Control coils may want to check the status of your mount washers.
(note: I had my AGX's on the stiffest settings all around when this happened, so partially my fault for driving that way on surface streets)
