I have a pair of H&R 20 mm spacers with the extended lugs for sale. I had these on my 06 e90 330i. It was a Pre-LCI and gave the rear wheels a perfect flush fitment. I don't know about LCI's but I would imagine it would be wider since their track is wider.
I added some pictures below. They are in great shape. I am asking $90 shipped or BO.
