Hey Yoshi, I checked today while I was in the parking lot for Home Depot. There is a rubber cylinder on the strut shaft so I am thinking the bumpstops are there (sigh of relief

). Yes, I did notice the AGX's make the familiar bicycle pump noise, and I guess that's not going away. But since I did not want to wait for coil insulators, I bought 20' of clear PVC tubing from Home Depot. I'm going to cut them in the shape of a helix so I can wrap them on the coils without removing the struts from the car. Hopefully this will help.
thanks!
