Long story how this happened however I was going to "upgrade" my front calipers to BMW 320i calipers. I was having the caliper flange machined and (long story) the flange is now a little too thin. The specs call for the flange to be 0.587" +/-0.005" and mine measure 0.539". Other than the obvious- scrap them and start with a new set- do I have any options? Can I can get a perfectly measured, very thin spacer and put it between the strut and the flange?
Also, are 19mm master cylinders needed for 320i calipers?
