might get 3mm spacers made up for the e30 hub 57.1mm with only 4 holes in it for the bolts. They will be aluminum. i needed 3mm spacers for the front of my car, and the universal spacers are junk so i thought i would get some laser cut. and then there nice and perfect. so i would get a bunch made up if there is interest in them, also might get like 5mm ones made up. with the 3mm spacers your hub will still stick out i think so there is no need for hub centric rings on them. will just be a flat plate. not sure exactly what they will cost let me know if your interested at all, and any other suggestions to this would be great.
