EBC | Yellowstuff Brake Pad 4000 Series Sport Set | Focus MK2 ST225

SKU: DP41574R
Technical Data & Performance Profile: EBC Brakes Yellowstuff Fast Street Compound
 
Compound Architecture: A proprietary, British-engineered friction material formulated with high-density aramid fibers, entirely free of copper and restricted heavy metals. This advanced matrix is engineered for exceptional thermal stability and reduced environmental impact.
 
Primary Performance Characteristic: Engineered to deliver a ~30% increase in initial bite and dynamic friction over traditional OE-style street pads. This translates to measurable gains in stopping power and reduced pedal effort, providing a decisive performance margin for modern, high-powered vehicles.
 
Friction Stability Profile: Features an exceptionally stable static and dynamic friction coefficient (μ) of ~0.48μ. Critically, this high coefficient is maintained with minimal fade from ambient temperatures up to 450°C, a threshold typically associated with light race use. This flat-fade curve ensures consistent pedal feel and braking performance during demanding street or spirited canyon driving.
 
Application Engineering & Compliance:
 
  • Target Application: The definitive fast-street upgrade for premium sedans, sports cars, and high-performance vehicles. Engineered for drivers seeking maximum stopping power for public roads without the acoustic or cold-performance compromises of full-race compounds.
  • Regulatory Approval: ECE R-90 certified, guaranteeing homologated performance equivalence to original equipment for road use in over 60 countries. This certification validates safety, consistency, and durability metrics.
  • NVH Mitigation: Each pad is precision shimmed (to dampen vibration), chamfered (to prevent initial grab and noise), and slotted (to degas and reduce glazing). This tri-phase design is implemented specifically to promote silent, judder-free operation in daily driving conditions.
 
Operational Protocol & Limitations:
  • Use Case Directive: Exclusively for fast street and highway use. Not designed or warranted for circuit, track day, or competition driving. Extended track use may exceed the compound's optimal thermal operating window.
  • Critical Bed-In Procedure: The high-performance compound requires a meticulous, controlled bedding-in procedure to transfer a uniform friction layer to the rotor. For users planning occasional track exploration, EBC recommends pre-bedding the pads over several hundred miles of street driving to establish this critical layer before any track excursion.
  • Track Alternative: For drivers prioritizing rapid readiness for track days, the EBC Bluestuff R-90 compound is recommended as a direct alternative, offering similar ECE R-90 compliance with a faster, more aggressive bed-in characteristic suited to mixed use.
 
Provenance: The friction stability and performance envelope of this Yellowstuff formulation have been validated in competitive environments, notably contributing to championship wins in production-based series such as the MX-5 Cup, confirming its efficacy in lightweight, high-demand applications.
Summary: The Yellowstuff compound represents a calibrated intersection of extreme performance and road legality. It delivers race-proven friction stability and a significant power increase for the street, while engineered features and strict certification ensure refinement and reliability for premium road vehicles.
