Bilstein PSS9 Install instructions

Recommended Posts

Does anyone have PSS9 install instructions for a 996 C2 (2000)? I wanted to see what parts are re-used so I can order new ones.

Also, some posts I have read indicate that the PSS9 is only adjustable for rebound and not compression damping. However, the Bilstein literature on their website indicates that there is adjustment for both rebound and compression. Are there 2 separated knobs for independent adjustment of the compression and rebound?

One knob does compression and rebound at the same time. I have a complete list of parts needed, they are shown on the PSS10 instructions which you can download direct from Bilstein or I can email them to you. PM me with your email address. The PSS9 instructions show a representative square which says something on the order of "reuse OE parts here". On the fronts, you reuse everything except the bump stops & springs (duh). On the rear, same, but you do not used the slanted spring spacers. If you buy all new parts, including the 4 replacement one time caliper bolts, it will run you about $600 from Suncoast. The 8 concave washers (strut stops on the PET) are $140. I chose to reuse those, and just replace the rubber parts and bearings. I also used the X74 front upper strut mounts (rears are the same, stock or X74), which were about $20 each more than the EO upper strut mount. So mine was about $540 total. Ialso bought the 997 GT3 brake air scoops, ($22 a set, larger, nicer, brakes run cooler) and the Porsche engine protection pan ($86).
