I have new OEM short bump stops for your BMW.
These are OEM parts from E36 M3 (front) and E85 Z4 (rear).
They are shorter than stock bump stops which makes them necessary addition to those looking to swap their suspension to aftermarket spring/shock set (ie. Koni yellow/H&R, Eibach, and etc).
I have one and half set available.
Full set includes 2 front E36 M3 bump stops and 2 rear E85 Z4 bump stops with shock covers.
This is available for $75 shipped (US ground only).
Half set includes 2 rear E85 Z4 bump stops with shock covers.
This is available for $35 shipped (US ground only).
I am currently using full set together with my full Eibach shock and spring combo. They work great!
