dd123, I'm very happy to see you got your struts/springs installed! I'm also very happy to see that between you and MattV (and others), you seemed to have found a solution to all that racket that came with the new setup.
Because you know what? Since I've had my tokico blue/RB setup, I've had a lot of noise (I think I told you that before...) that just isn't resolving. So I'm definitely going to try the washers - and thanks to MattV for making a DIY on it!.
If that doesn't fix it, I'll have to look at tightening up those "metal cans" on the rear struts because that's where I hear all my rattling. I sure hope I don't have to pull the struts out though...
Thanks guys!
