The EBC DP52274NDX is a front brake pad set built on Bluestuff NDX, which the manufacturer describes as a high-friction version at 0.52 Mu. The pads are bonded to their steel backing plates with the patented NUCAP NRS hook system, and they are baked and ground with high-volume Vee grooves to clear track debris. The manufacturer rates them for rotor temperatures of 0-550°C, so they suit a Focus RS whose braking demands have outgrown a stock pad.
The main reason to pick this over a cheaper track pad is the front-specific grade. The manufacturer makes a lower-friction Bluestuff B version at 0.42μ for lighter cars and rear axles, so confirm you are ordering the NDX front compound. The listed application is the 2016-2018 Ford Focus RS. Sources differ on the end year, so check the manufacturer's application guide before you buy. Long-tail searches for this part include Focus RS track pads, Bluestuff NDX front pads, and 2016-2018 Focus RS Brembo pad upgrade.
The manufacturer says in street use the lifetime is considerable, with 20,000 miles and upwards expected, even when driving hard.
Owners on user forums report that they often leave the caliper in place and turn the wheel to full lock for working room.
The manufacturer advises you to inspect pads every 30 laps and discard when friction material is down to one eighth of an inch or 3mm to avoid fade.
Front pad changes on the Focus RS are a moderate DIY job. Owners on user forums suggest a 13mm socket and wrench, a torque wrench, a small punch, an 8mm punch, a piston spreader, and brake cleaner. Expect the pins to be the hard part. Owners report that the middle pin has a retaining bolt, and rust can make it difficult to drive out. Cleaning the pins and their spring with a wire brush and penetrant before you start helps. Clean the carriers and avoid scoring the caliper bores when you spread the pistons.
