I have for sale a set of AKG rear shock mounts. They are brand New, Never installed. I took one out of the plastic just to check it out but the other is still in it's plastic.
I believe these are only for e46.
From AKG's site:
Rear Shock Mount Set - 10mm
For BMW e30, e36, e46, Z3, Z4
7075 aircraft-quality aluminum, hard anodized
U.S. Military Spec Polyurethane (replaceable) bushing and stainless steel hardware
Set of two
Also have with them a set of Rear shock mount reinforcement plates. They can be sold with the rsm's or individually if I have already sold the RSM's.
Bought them to replace the sh!tty OEM RSMs but ended up getting a set of coilovers that came with RSMs with it so I don't need these anymore.
Rear Shock Mounts (RSM's) and Reinforcement Plates - $100
Just RSM's - $90
Just Reinforcement Plates (likely don't want to sell unless RSMs have a buyer) - $15
Thanks for looking.
