Bilstein shock QUESTION??

[dirkdiggler]

What do the little tapered washer that comes with the Bilstein shocks actually do?

The OEM shocks do not have this washer on them??

I put some brand new Front shocks on my Boxster last-night and my mechanic buddy didnt know what that little washer was for and figured since the old shocks didnt have them, we didnt need to install on the replacement shocks.

So pretty much I have my brand new Bilstein shocks installed without those little tapered washers on the shaft.

ANY ISSUES I CAN ANTICIPATE???
