EBC SG2FK-041 Fully-Floating Slotted 2-Piece Front Brake Rotor Replacement Ring 355mm

The EBC SG2FK-041 is a high-performance replacement friction ring designed for EBC Brakes Racing's Balanced Brake Kits. This fully-floating 2-piece front brake rotor ring delivers race-proven technology for both street and track applications, featuring a 355mm diameter with 32mm initial thickness and 30mm minimum wear thickness.

Premium G3500 Disc Alloy Construction:

Cast from EBC's highest-grade G3500 disc alloy, this friction ring features high-carbon and high-copper metallurgy derived from race technology. This advanced material composition provides superior thermal conductivity and exceptional heat cycling durability, allowing the rotor to withstand extreme braking conditions while maintaining consistent performance during hard driving or track use.

Advanced Cooling Technology:

• 48 curved directionally-handed vanes oriented left and right for proper rotation direction
• Precision molding resin sand casting creates smooth internal surfaces for improved airflow
• Enhanced vane design maximizes cooling efficiency and maintains lower operating temperatures
• Helps delay the start of brake fade during aggressive driving
• Curved slot pattern efficiently evacuates brake dust and gases

Fully-Floating Design Benefits:

The cast iron friction ring floats on EBC's patented SD-Drive technology bobbins, allowing up to 3mm of thermal expansion and contraction under extreme braking heat. This floating design, combined with anti-rattle spring clips at each bobbin location, ensures quiet operation without the common noise issues found in other full-race 2-piece systems. All bobbins are crafted from single-piece stainless steel to prevent corrosion and ensure long-term free-floating performance.

Cost-Effective Maintenance:

When the friction ring reaches minimum thickness, it can be replaced independently while reusing the center hub and stainless bobbins, significantly reducing long-term running costs compared to replacing complete rotor assemblies.

Testing and Quality:

EBC's 2-piece rotors are designed, manufactured, and run-out tested in the UK. In R90 Thermal Fatigue Testing, these rotors completed two full test cycles back-to-back with zero disc cracking, outperforming most OE discs by a factor of over 4x. Each ring is balance checked, metallurgy verified, and precision double-disc ground for perfect accuracy and flatness to within microns.

Application:

This SG2FK-041 replacement ring is specifically designed for vehicles equipped with EBC Brakes Racing's 6-pot Big Brake Kits and should only be used as a replacement component for these systems. The black heat-resistant finish on the friction ring quickly wears to natural iron in the swept area while protecting unswept areas from corrosion.
