Just finished installing Carbotech XP10 in the front in preparation for a track day on Friday. Went very smoothly. The job is easy and very similar to the E46 indeed.
The rattle clip was indeed a piece of cake to remove: Just slide a screw driver under the large flat piece of the clip in the middle and pull away (from the center of the wheel) to dislodge the middle tab from the caliper holding feature.
A couple of interesting notes though:
- The M3 has a brake wear sensor on both sides in the front. That was a surprised to me. The E46 had it on one side only.
- The Carbotech pads do not have a recess in the pad material for the brake wear sensor. I wrapped the sensor cable about the brake line.
