I have been working with a friend who is in the sheet metal industry and we have developed these two brackets. There are two types. One is short and more suited to F1/GP cars(BWA style) and the other has longer arms and is 1.0mm offset. Not to say you couldnt file the bearing holes and give yourself a short offset bracket using type 1. The material is spackle finish panel steel. I can bend it on the fold lines with thumbs and pliers. It also solders well. Costs are 2.00GBP per piece plus shipping. PM me for more details if you wish.
