Comparing carbon ceramic pad compounds against Endless W007 and Pagid RSC1 comes down to operating temperature windows, rotor wear dynamics, and real-world noise tolerance. Standard original equipment carbon ceramic pads prioritize immediate cold bite and quiet daily operation, but they rapidly degrade under sustained circuit use. Pagid RSC1 serves as an all-round track-day compound that expands thermal capacity while maintaining acceptable street manners, whereas Endless W007 is a dedicated semi-metallic motorsport pad built strictly for high-heat circuit endurance at the expense of cold-temperature quietness.

Key Context
Carbon ceramic braking systems rely on discs manufactured from carbon-fiber-reinforced silicon carbide (C/SiC). Unlike conventional cast iron setups where semi-metallic pads create an abrasive cutting action, carbon ceramic systems function through an adherent transfer layer deposited directly onto the ceramic surface matrix.
Matching the friction compound to the rotor substrate is essential. Running an abrasive iron-disc pad or an improper compound will strip away the smooth silicon carbide friction surface, resulting in catastrophic rotor grooving and replacement bills exceeding dealer estimates. Conversely, taking soft road-oriented factory pads onto a racetrack causes rapid resin breakdown, uneven friction deposits, and brake pedal fade.
When performance owners evaluate alternatives to costly dealership pads, Endless W007 and Pagid RSC1 represent the two most common motorsport-derived benchmarks. Understanding how their mechanical properties interact with continuous-fiber and chopped-fiber carbon ceramic rotors, such as the direct-replacement assemblies supplied by ForzaCCB, ensures your braking system delivers consistent stopping force without premature disc degradation.
Technical Comparison Across Operating Windows, Bite, and Rotor Wear
Thermal Ceilings and High-Temperature Fade Resistance
Factory carbon ceramic pads are engineered around standard road driving cycles, where ambient temperatures and quiet stops are paramount. Under repeated hard stops from high speeds, OEM pad core temperatures often cross 550 degrees Celsius, leading to rapid vaporization of binding resins and noticeable pedal elongation.
Pagid RSC1 raises this threshold by utilizing a low-metallic ceramic resin matrix designed to remain structurally stable up to roughly 750 degrees Celsius. This headroom prevents pad softening during typical twenty-minute track day sessions on high-performance platforms like Porsche GT models, McLaren Super Series, and Aston Martin sports cars.
Endless W007 shifts the envelope further toward pure motorsport duty cycles. Engineered specifically for Brembo SGL CCM and Porsche PCCB rotors, W007 operates comfortably in extreme thermal environments exceeding 800 degrees Celsius, virtually eliminating thermal fade under sustained circuit abuse.
- OEM pads: Optimized for temperatures below 550 degrees Celsius; prone to resin glazing during sustained track sessions.
- Pagid RSC1: Operating window spans roughly 100 to 750 degrees Celsius; resilient under fast road and intermediate track-day heat.
- Endless W007: Operating window spans 200 to over 800 degrees Celsius; specifically designed for heavy circuit lapping.
Friction Coefficient Curves and Pedal Modulation
The friction coefficient, or Mu level, dictates how much braking torque is delivered relative to hydraulic line pressure. Factory pads exhibit a stable friction rating of approximately 0.36 to 0.40 Mu, delivering predictable bite instantly from a cold start but tapering downward as caliper temperatures peak.
Pagid RSC1 introduces a progressive torque response with a nominal friction level hovering between 0.40 and 0.44 Mu. The initial bite is firm without feeling grabby, allowing drivers to modulate pedal pressure smoothly and execute precise trail-braking maneuvers without triggering aggressive ABS intervention.
Endless W007 delivers a steeper torque curve with an average friction coefficient between 0.44 and 0.48 Mu under working temperature. The initial attack is noticeably sharper than RSC1, requiring a deliberate, calibrated pedal input to avoid over-slowing the vehicle before corner entry.
- Pedal response on OEM pads feels gradual and power-assisted, designed to minimize passenger discomfort in urban traffic.
- Pagid RSC1 provides a linear, highly communicable pedal feel that mirrors brake fluid pressure across varied cornering loads.
- Endless W007 yields a high-rigidity pedal sensation that demands physical pressure and heat to achieve optimum modulation.
Rotor Surface Preservation and Transfer Layer Dynamics
A primary concern for track drivers running carbon ceramic rotors is disc consumption. Rather than wearing down mechanically like iron discs, carbon ceramic rotors degrade primarily through chemical oxidation of carbon fibers when internal core temperatures exceed 600 degrees Celsius without an adequate friction barrier.
Pagid RSC1 is widely regarded as one of the kindest compounds available for carbon ceramic rotors. Its organic-ceramic composition lays down a thin, uniform transfer layer that protects the silicon carbide friction face from localized hot spots, significantly extending disc operational life on track.
Endless W007 relies on a specialized semi-metallic formulation designed to transfer a durable sacrificial film at high kinetic energy levels. While it is remarkably safe on ceramic discs compared to generic motorsport pads, running W007 below its intended thermal window can cause uneven surface scavenging rather than proper material transfer.
- Transfer layer consistency is critical to prevent disc surface pitting and micro-cracking.
- Pagid RSC1 maintains an exceptionally smooth rotor interface with negligible disc material loss during mixed street and track use.
- Endless W007 preserves rotor integrity under continuous heat, but it requires regular thermal cycling to maintain a clean friction film.
NVH Levels, Cold Bite, and Street Drivability
Noise, vibration, and harshness (NVH) constitute the largest daily compromise when upgrading beyond factory brake pads. OEM compounds utilize complex chamfers, backing shims, and high-binder formulations to ensure near-silent braking under freezing or wet morning conditions.
Pagid RSC1 functions as a dual-purpose compound with acceptable street refinement. While light squeal may manifest under low-speed stops in city traffic, cold bite remains sufficient for safe morning transit to and from the circuit without requiring pre-warming.
Endless W007 makes very little pretense of street refinement. At sub-200-degree temperatures, W007 generates significant high-frequency brake squeal, produces noticeable metallic dust, and exhibits muted initial bite until sufficient heat is built into the caliper assemblies.
- OEM pads provide quiet stops and virtually imperceptible brake dust on painted alloy wheels.
- Pagid RSC1 exhibits mild-to-moderate low-speed squeal, which can often be mitigated with anti-squeal shims and ceramic paste.
- Endless W007 is loud during stop-and-go driving and is poorly suited for regular urban commuting.
Bed-In Protocols and Thermal Management Requirements
Proper bed-in procedures are vital to ensure long-term performance and prevent vibration. Because carbon ceramic discs do not wear down to match pad faces mechanically, the bedding process must establish a uniform molecular transfer layer through controlled thermal cycles.
Bedding Pagid RSC1 typically involves a staged series of moderate stops from 100 km/h down to 30 km/h, followed by three to four high-energy decelerations from highway speeds to bring the rotor face into its operating zone without stopping the vehicle completely.
Endless W007 demands a far more aggressive, track-focused bed-in routine. To properly cure the semi-metallic bonding agents, the pad must be brought to track temperatures through repeated high-speed stops on an open circuit, making complete bed-in on public highways virtually impractical.
- Always inspect rotor faces for existing pad transfer lines or glaze before bedding new compounds.
- Never allow the vehicle to come to a dead stop with the brake pedal held down during high-temperature bed-in cycles.
- When pairing either compound with replacement rotors from ForzaCCB, consult the manufacturer bedding guidelines to ensure full chemical bonding.
Practical Checklist
- Verify whether your driving profile is primarily road commuting, dual-purpose track days, or dedicated competitive lapping.
- Inspect the friction layer of your carbon ceramic rotors for surface roughness or oxidation before installing new pad compounds.
- Confirm that your brake fluid has a dry boiling point above 300 degrees Celsius before running Pagid RSC1 or Endless W007 on circuit.
- Measure your existing pad backing plate thickness to confirm exact caliper bridge and pin fitment across front and rear axles.
- Fit manufacturer-recommended anti-squeal shims and high-temperature paste if running Pagid RSC1 on mixed street and road-course duty.
- Reserve Endless W007 installations for dedicated circuit outings where high brake temperatures can be achieved consistently.
- Perform a complete chemical bed-in procedure immediately following installation to establish an unbroken friction transfer film.

Can I run Endless W007 pads as a daily street brake pad?
Endless W007 is not recommended for daily street driving. Because it is a dedicated circuit compound, it lacks optimal initial bite at ambient temperatures and generates persistent, loud brake squeal during urban low-speed stops.
Does Pagid RSC1 produce more brake dust than factory carbon ceramic pads?
Yes, Pagid RSC1 produces slightly more brake dust than factory road pads due to its higher-friction ceramic formulation. However, the dust is significantly lower and less corrosive than what is typical of traditional semi-metallic pads on iron rotors.
Can I alternate between OEM pads and track compounds on the same carbon ceramic discs?
Alternating compounds on carbon ceramic discs is possible, but it requires cleaning the rotor face or conducting a careful re-bedding sequence. Intermixing different pad chemistries without bedding can cause uneven transfer layers, leading to pedal shudder.
How does Endless W008 differ from the W007 compound?
Endless W008 was developed directly from the W007 program as a dual-purpose street and circuit compound. It offers lower operating temperatures, reduced noise levels, and broader street usability, whereas W007 is strictly a high-heat circuit pad.
Will running Pagid RSC1 or Endless W007 accelerate carbon ceramic rotor wear?
Both Pagid RSC1 and Endless W007 are specifically formulated with non-aggressive binders that protect carbon-fiber-reinforced silicon carbide matrices. On the racetrack, both compounds actually protect rotors from the severe oxidation caused by overheating factory road pads.
