Hey, first time i've tried this. i have just replaced the control arms and bushes on my E36 (1995 signature). After seeing the price of new control arms ($350 + $90 for second ball joint) i was told the geometry on the E30 control arm is the same. No floating ball joint on the outer, but i couldn't find what difference that was anyway. i seem to be having some problems getting an alignment. The place where i got the alignment done is saying my rack is in need of repair, my mechanic (who was working for BMW so he knows his stuff) says there is nothing wrong with anything but the alignment. He doesn't know (cos BMW would never use E30 parts in a E36) if the parts are compatible. does anyone know if these parts can be used, or have i got to spend another $900.
