Right people I know these calipers a bit of a tight squeeze under 15inch puma wheels.I know people trim the calipers down with a grinder.So which parts of the caliper need to be trimmed down so they dont catch the inside of the wheels.

I know some people might think this is dodgey but its only a bit that needs to be trimmed off.

So using the pic can someone point out which parts of the caliper need to be trimmed/grinded.
