If anyone is looking for a NEW Rear Axle Carrier, a foreign car salvage/repair yard in my area supposedly has a BRAND NEW one in stock.
33-31-1-090-957 - $390
This is $825 at PelicanParts.
Save $435 PM me for details. I am NOT affiliated with this place at all, but I just stumbled across it and thought it might help a fellow 318ti.org member!
This place also has NEW 318ti trailing arms for super cheap. See here:
