Hi all,

My shop just called to inform the "pre-owned" Bilstein coilover set has missing parts and cannot complete the install without.

Attached is the diagram of missing parts, does anyone where these items can be sourced?

Thank you,

 

Missing parts are:
Front - 4 conical washers PASM specific
Rear - 2 rubber ring gasket

I have no clue where these can be purchased

 

From Bilstein:

Part number for washers - E4-SB2-Z026A03 which are not available in the US and have to be ordered from Germany.


Part number for the isolator - E4-XK6-Z002A01 which are stocked in the US and can be ordered through any Bilstein distributor.

 

Reach out to one of the bigger racing shops here or on Rennlist (Tom at TPC Racing, Scott at Fabspeed, Sharkwerks, etc.). It's fairly common to upgrade a C2S/C4S to Bilstein Damptronic coilovers and replace the top strut mounts with GT3 style camber plates (OEM GT3, Tarret, Rennline, others). This means all the Bilstein parts at the top of the shock are not installed. Instead they are replaced with a more traditional coilover spring perch and the camber plates. I bet they have these extra Bilstein parts you need laying around their shop.

 

Make sense thank for chimes in.
