For those interested in assembling their own brake kit based on the CP9660 and CP9668 AP Racing Pro5000R calipers, the N15 Design radial brackets allow the calipers to be adapted to the E46 M3.
AP Racing offers nearly all of its calipers and other brake kit components as off the shelf parts.
CAD designed and CNC machined from 6061 aluminum, these brackets fit and perform perfectly on track. High grade motorsport studs manufactured in Germany are pre-installed along with high quality metric jet nuts for caliper clearance. Hardware of the proper length and grade to mount to the spindle/upright is also included.
