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? |

19mm master is needed or your peddle travel will be scary long. (IMG:style_emoticons/default/unsure.gif) The 320 piston fluid volume is more than the stock 914 caliper. The 320 caliper is not optimum in my opinion. First the machine work then the pads ride high on the rotor and actually over the top I guess. The BMW 2002 4 piston is better and a direct bolt on with the exception of the duel lines. They are small and light unlike the Volvo 4 piston units. I have them on my car.

Do you need a 19mm MC for the 2002 calipers? |
