Brake Disc Features:                                                   

•Equivalent to OE design 

•Smooth and quick stop 

•Anti-rust 

•Low noise, low dust 

•Optimal thermal performance 

• The rear brakes don’t get the glory, but they get the work—especially when you’re carrying cargo, towing, or descending a long grade. This 316mm x 20mm disc was engineered to handle exactly those overlooked duties, delivering a thermal reserve that keeps rear axle temperatures in check even when the fronts are working overtime. The drilled and slotted surface isn’t just for show; it serves a dual purpose. The holes vent trapped gases that reduce pad bite, while the slots act as squeegees, wiping the friction face clean of debris and glazed material. The result is a consistently fresh pad-to-rotor interface that yields shorter stopping distances and a pedal that feels solid and responsive stop after stop.

• Corrosion is the silent enemy of any brake component, particularly for vehicles that live near the ocean or endure harsh winter salting. That is why this disc comes with a factory-applied zinc coating that sacrifices itself to protect the underlying iron, effectively stopping rust before it starts. For those who prefer alternative preservation methods, we also offer oiled, painted, and specialized coated options—each tailored to specific storage or operating environments. The coating extends to the hub mounting face, a thoughtful detail that prevents the disc from seizing to the wheel flange, saving your mechanic from the dreaded sledgehammer-and-torch routine during future service.

• Let’s talk about the bearing-integrated variant, because it changes the installation game entirely. Instead of pressing a separate hub bearing into the disc, this version arrives pre-assembled, with the bearing already seated and greased to OE tolerances. This not only cuts labor time in half but also eliminates the risk of misalignment that can shorten bearing life. Fleet operators and commercial vehicle workshops especially appreciate this feature—it turns a complex two-hour job into a straightforward bolt-on replacement, keeping vehicles on the road and earning revenue rather than occupying a bay.

• The thermal behavior on the rear axle follows a different rhythm than the front. Rear discs rarely see the intense heat spikes of emergency stops, but they endure longer periods of moderate heat during highway cruising and stop-and-go traffic. The internal ventilation vanes on this disc are oriented specifically to maximize airflow capture in forward rotation, maintaining a stable temperature plateau that prevents the gradual heat soak which can soften pedal modulation over extended drives. This consistent thermal environment also helps the electronic stability control and ABS systems function with greater precision, because they rely on predictable friction characteristics at each corner.

• Durability testing for this disc involved hundreds of thermal shock cycles—alternating between extreme cold and operational temperatures—to simulate a decade of real-world use. The high-carbon G3000 iron formulation proved exceptionally resistant to micro-cracking and run-out, maintaining a flat, true surface that prevents the pedal pulsation that drives drivers to distraction. When paired with compatible brake pads, the disc achieves a wear pattern that remains remarkably uniform, extending the replacement interval and reducing overall cost of ownership for SUBARU owners who value reliability over flash.

• From a manufacturing standpoint, every disc is precision-turned and ground to achieve a surface finish that promotes rapid, even bedding with new pads. The absence of run-out and minimal disc thickness variation means you won’t experience that disconcerting steering wheel shake during high-speed braking—a common complaint with lower-quality rotors. The machining process is consistent across every unit, thanks to IATF 16949-certified production controls that keep dimensional variations within microns.

• Global compliance is non-negotiable. This disc carries ECE R90 certification, confirming that its braking efficiency matches or exceeds the original equipment reference across all mandatory test conditions. It also meets AMECA standards for the commercial vehicle segment, making it a viable choice for regulated fleets. Whether you are servicing a personal SUBARU in North America, maintaining a delivery van in South America, or operating a commercial fleet in Eastern Europe, this disc delivers documented, traceable quality backed by ISO14001 and ISO45001 certifications. It is ready to install right out of the box—no rust-scraping, no modifications, just dependable stopping power mile after mile.

Brake Pad Features:

•High performance 

•Long-life service 

•Anti-thermal-fading

•Low noise, low dust 

•Environmental-friendly

• Every disc deserves a pad that complements its character, and this rear pad set was formulated specifically with drilled and slotted rotors in mind. The friction compound leans toward a low-metallic, organic hybrid blend that produces a gentle, non-abrasive rubbing action—perfect for preserving the disc's drilled edges and slotted channels from premature wear. The result is a system that works as a cohesive unit, not two components fighting each other. You get consistent pedal feel, reduced rotor scoring, and a significant drop in the high-frequency squeal that often plagues aftermarket combinations.

• One aspect that sets this pad apart is its low-drag formulation. Rear brakes naturally experience less clamping force than fronts, but they also have a tendency to drag slightly against the disc when the pedal is released—creating unwanted friction that hurts fuel efficiency and generates unnecessary heat. Our compound incorporates a proprietary lubricant dispersion that minimizes this residual drag, allowing the caliper to retract more fully after each stop. The improvement is subtle but measurable: better mileage, cooler running temperatures, and reduced dust accumulation on the rear wheels, which tend to collect grime more visibly than fronts.

• Noise control for the rear axle requires a different approach than the front. The acoustic environment is quieter back there, which means even minor squeaks become annoyingly noticeable. We tackled this by integrating a noise-damping shim that uses a viscoelastic core, tuned specifically to the resonant frequencies of SUBARU rear brake systems. The shim absorbs vibrations before they can travel through the suspension and into the cabin, so you enjoy the same hushed, composed ride whether you are cruising on the highway or creeping through a parking lot—without the embarrassing chirp at every slow-speed stop.

• Dust reduction is another front where this pad excels—not just for aesthetics, but for the health of the wheel bearings and suspension components. Brake dust contains metallic particles that, when wet, form an abrasive sludge that can accelerate wear on nearby seals and bushings. Our ceramic-infused, copper-free binder system dramatically cuts down on particle generation. The dust that does form is light-colored and non-staining, rinsing away effortlessly during routine washes rather than bonding to the wheel surface like traditional semi-metallic pads.

• Thermal stability across extreme temperatures remains a given, with the pad performing reliably from -50°C to 700°C. But here, the focus is on the lower end of the spectrum—because rear brakes often run cooler, and cold pads can feel wooden or unresponsive. Our formulation includes a special low-temperature friction booster that ensures the first stop of the day feels as confident as the hundredth, even when the frost is thick on the windshield. This characteristic is particularly valued in northern climates, where drivers need immediate stopping power without the unsettling delay of warming up the brakes.

• Longevity is enhanced not by making the pad harder, but by making it wear more evenly. The compound uses a balanced distribution of reinforcing fibers that resist tapering, a common issue where the leading edge wears faster than the trailing edge. By maintaining a flat, parallel wear face throughout its life, this pad keeps the contact patch full and effective, reducing the frequency of replacement and preventing the disc from being scored by uneven material. An integrated mechanical wear indicator gives a clear audible warning at the recommended replacement point, taking the guesswork out of maintenance scheduling.

• Like the disc, this pad is fully ECE R90 certified, verified through dynamometer testing that compares its performance against the OE reference. It meets all regulatory requirements for friction coefficient, speed sensitivity, and hot/cold performance, giving both independent workshops and fleet managers a defensible compliance record. The backing plate is coated with a durable anti-corrosion layer that resists rust creep, and the entire set is packaged with the necessary hardware clips and springs to ensure a rattle-free fit within the SUBARU rear caliper. With the same IATF16949 and ISO certifications backing it, this pad offers the same level of global quality assurance as its disc counterpart—because a brake system is only as strong as its weakest link, and we build every link to last.
