The EBC Yellowstuff DP43018R is a rear pad in the manufacturer's high-friction line, built on an aramid-fibre compound for faster street cars, SUVs, and light track use. The case for paying more than for a basic replacement pad is cold bite and heat tolerance. The manufacturer also cites an excellent cold bite coupled with high-temperature fade resistance, plus drastically reduced stopping distances compared to OE. The manufacturer says the range is easy on rotors, which matters if you plan to keep your rear discs in service. Expect more dust in exchange for that bite.
Fitment is the first thing to verify. Listings disagree on the RLX year span, so have the manufacturer confirm the application against your VIN before ordering. The rear job itself is manageable with basic tools, but the electric parking brake changes the routine. Owners on user forums describe a Torx 25 to remove 2 bolts that attach the black actuator to the caliper, and they note that the piston must be wound back before the new pads will fit. Once the pads are in, the forum advice is to cycle the parking brake so the system relearns its position. Pair this with a proper bedding procedure, since the manufacturer's Brake-In coating is designed to accelerate pad bed-in.

No. The manufacturer states that Yellowstuff pads are not rated as low dust, so expect to clean your wheels more often than you would with a low-dust compound.
Owners on user forums recommend setting and releasing the electric parking brake several times after reassembly so the system relearns the correct position.
Rear pad replacement on the RLX is a reasonable DIY job, but the electric parking brake actuator is the main gotcha. Owners on user forums report that the actuator is attached to the caliper with two Torx 25 bolts, and that the caliper piston must be turned back to make room for the thicker new pads. Before you start, check the hose routing so you don't kink the brake line, and grease the pad contact points and slide pins as you reassemble. After installation, cycle the parking brake several times to reset it, then bed the pads in gradually before any hard stops.
