Installing PSS9's - want to prevent "clunking"
Does anyone have the part numbers for Bilstein slip rings (washers) that help prevent the dreaded clunking noise? I believe they are only $1.25 ea or something like that. I want to do it right the first time. Any help would be greatly appreciated.
Best regards, -Josh

Here you go for 2 WD:
If you looked at your original PSS9/10, the bottom, helper spring, rides on top of a large blue plastic washer, between the spring and the adjustable spring perch. You can order another one for the top of the front helper spring, (2 total needed) 60mm, part number E4-XK6-Z002A00 for $1.50 each. You can also order 70mm ones for the top main springs, front & rear, and the rear helper springs, part number E4-XK6-Z002A01, 10 required, same price. However, the lip on the top spring cup, under the RSM, is pretty shallow, and reducing it by 1.5mm might not be too good an idea. Also, how much clunking comes form the rear, anyway? If you install them, order 2 new main top nuts, as the nylon lock ones are one use only. All the parts form Bilstein, 12 washers and 2 nuts, was $25 shipped. Naturally. as the washers are 1.5mm thick, if you add 3 new ones, then the car is raised 4.5mm higher than the designed range, and that must be accounted for in keeping it within Bilsteins lowering limits. Bilstein east coast is 1-800-745-4636, ask for Parts or Kieth Robertson. They ship out of CA, so you might also want to call CA direct.
Front locking nylon nuts (M14x1.5)= 2 x #2517670
