so i bought a set of pss9 used and it didn't come with the proper bilstein donuts (bumpstops). it's missing the top ones and are circled in red (see pick below). has anyone tried running the oem ones w/o problems?

 

I run the oem ones...havent had a problem in 10K miles...cant say its proper for sure, but worked for me

 

thanks ikeyballz.

so if anyone is wondering how much EACH donut costs from bilstein, it's $121.

 

^wow. thats insane. lol, I just used the OEM top hat with OEM everything..

 

well i know you're supposed to use the oem tophat but use the bilstein donuts instead.

 

ok, i just realized i'm missing both of the donuts.

anyone else running oem donuts w/o problems?

 

called bilstein, they said it's no problem if hte oem donuts fit and are roughly the same length....

but oem donut inner diameter is smaller than the strut shaft so FML.

trying to get a refund now...
