need to space the caliper mount 1mm away from the hub with a washer to centre the mount to the disc.
my gtir disc needed 1mm lathing off the edge cos it was rubbing the caliper when hot.
the gtir disc centre hole is slightly bigger than the micra hub so to keep the disc centred you can either machine an insert ring or just bulk up the hub with some ducktape.
bigger wheels required. least 14" but preferably 15"
