Hi all,

I just bought some calipers from an early 80's BMW 320i for the teener. I've heard that they have to be machined slightly to fit. Does anybody know how much material has to be taken off, or the best way to measure how much to remove? They will be going on to a 74 2.0L. I haven't tried to install them yet, but I'm assuming that the mounting ears need to be machined down a little so that the rotor is perfectly centered in the caliper, correct?

I spoke with an engineer at Wilwood, he said a little overhang is no big deal, not sure how much you get with the Volvo calipers...the biggest issue is to make sure that you change your pads before they could ever get to the point of contacting each other due to the overhang of the pads and the narrowing of the rotor.....in fact the Winston Cup car at Brads old shop had about 1/4" to 3/8" worth of overhang on it's massive brakes.
This was an ex-roush or one of those big name, big dollar cars, not some garage built contraption

of course too much overhang and you start to loose the advantage of going to a caliper with more surface area for the pads.
