The EBC DP32133C is a rear brake pad set from the Redstuff line. The manufacturer describes the compound as an aramid fibre base enhanced with ceramic granules, with no copper, lead, or steel fibre. For an F80 BMW M3 3.0 Twin Turbo, that makes it a street-focused upgrade over stock pads. The manufacturer also says the high-friction formula improves brake effect by up to 15%, and it produces far less dust than many semi-metallic pads. Dust is easy to rinse off alloy wheels, and the aramid material does not etch wheel finishes. Expect a bed-in period of about 500 km before full performance, according to the manufacturer.
Buy this set if you want a fast-road rear pad that keeps wheels cleaner than typical performance compounds while staying ECE R90 approved for road use. The Red Brake-In surface coating helps the pads and rotors mate faster after installation. Owners on user forums commonly report that the job is straightforward on the F80 M3, but the pad wear sensor needs to be removed or replaced, and the brake fluid reservoir should be watched while the pistons are pushed back. Search terms this fits include F80 M3 rear brake pads, DP32133C rear pads, Redstuff ceramic M3 pads, and low dust M3 rear pad upgrade.
The manufacturer states that Redstuff takes approximately 500 km to fully bed down and show its full performance. The Red Brake-In coating on the pad surface is meant to speed up the early bedding stage.
The manufacturer states that Redstuff is fully ECE R90 brake safety tested and approved for road use.
Owners on user forums report that the sensor can be unclipped from the old pad and reattached to the new one, or swapped for a new sensor if preferred. Leaving it disconnected is not a suitable fix, so keep it connected and secured.
Owners on user forums describe this as a manageable driveway job with basic tools. Remove the wheel, then use a small punch and hammer to drive out the two caliper pins and the retaining clip. Push the pistons back with a pad spreader or a clamp, which is when the brake fluid reservoir can overflow, so check the level and consider siphoning some fluid off first. Slide the old pads out, move the wear sensor, and slide in the new pads. Many owners apply anti-squeal compound to the backing plates beforehand. Forum discussions also mention rattle clips and pin orientation as things to check. Torque values were not confirmed in this research, so use the manufacturer's service data for final tightening.
