EBC SG2FK-080 Fully-Floating 2-Piece Racing Brake Rotor

The EBC SG2FK-080 is a high-performance, fully-floating two-piece brake rotor engineered for drivers who demand race-level braking precision. As part of EBC Brakes Racing's Balanced Brake Kit™ (SG2FK series), this rotor is purpose-built for road and track use, delivering a significant upgrade over standard one-piece cast rotors.

Key Features:

• Fully-Floating Design: The outer cast-iron friction ring is mounted on stainless steel bobbins, allowing it to expand freely under extreme heat — completely eliminating rotor warping.
• G3500 High-Carbon Cast Iron Friction Ring: Race-derived G3500-grade high-carbon, high-copper alloy provides superior crack resistance and outstanding thermal conductivity for heat dissipation.
• 48 Directionally Curved & Handed Vanes: Each rotor ring features 48 precision-curved vanes, handed left and right to ensure optimal airflow direction for maximum cooling efficiency and delayed brake fade.
• Aerospace-Grade Aluminium Bell: The mounting bell is precision machined from billet aerospace-grade aluminium and hard anodized for long-term durability — significantly lighter than cast iron alternatives.
• Curved Slotted Surface: Grooved (not drilled) rotor face allows brake pad gases to vent efficiently without creating stress points that lead to cracking — a key advantage over perforated OEM-style discs.
• Stainless Steel Bobbins: Rust-proof stainless steel bobbins ensure the rotor continues to float freely throughout its entire service life, even in daily road use.
• Anti-Rattle Spring Clips: Integrated spring clips eliminate off-brake rotor rattle for quiet, confident operation.
• Replaceable Friction Ring: The cast iron friction ring can be replaced independently, allowing the aluminium bell and bobbins to be reused — reducing long-term operating costs.
• Thermic Black Corrosion-Resistant Finish: Features EBC's latest thermic black coating for superior rust prevention and a clean, aggressive appearance.
• No Vehicle Modifications Required: Engineered as a direct bolt-on upgrade, seamlessly integrating with the OE brake caliper and hardware.
• Developed & Tested at EBC Headquarters: Engineered, manufactured, and run-out tested at EBC Brakes World Headquarters in Northampton, UK, following thousands of hours of dyno testing.

EBC's two-piece rotors have demonstrated exceptional durability in thermal fatigue testing, completing full back-to-back R90 test cycles with zero disc cracking — outperforming typical OEM rotors by a factor of over 4x. Whether used on the street or pushed to the limit on track, the EBC SG2FK-080 delivers a measurable improvement in braking performance, system endurance, and driver confidence.
