I have a pair of SPC adjustable rear chamber arms that will fit BMW E36 and E46. They are used but in very good condition. I took them off an E36. I wire brushed them clean now they're ready for paint.
These go for $130-180 each new, $260-360 per car. I'm asking $125 for the pair.
Let me know if you need more information. Shipping available on your dime.
From the SPC website:
"Get ±3° of camber adjustment on your BMW with this rear camber arm from SPC. Whether you need to improve tire life, add aggressive camber settings for the track, or just want a better handling car for the street, this is the arm for you. The high strength steel arm features fully forged ends and high durometer rubber bushings for long life, minimized noise, vibration, and harshness (NVH), and great handling characteristics. The easy to adjust turnbuckle and the remove & replace design makes this a hassle free install with lifetime adjustability. Sold each, order two to add camber adjustability to both sides of the car.
