EBC SG2FK-052 Racing 2-Piece Floating Brake Rotors for Big Brake Kit 380mm Swept Grooved

The EBC SG2FK-052 is a pair of high-performance 2-piece fully-floating brake rotors designed as direct replacement components for EBC Brakes Racing Balanced Brake Kits featuring 380mm front rotors. These premium racing rotors combine advanced engineering with track-proven durability for both street and track applications.

Advanced Floating Design:

• Genuine fully-floating construction with SD-Drive technology bobbins allowing up to 3mm of expansion and contraction under extreme braking heat
• Stainless steel bobbins machined from a single piece to prevent corrosion and ensure long-term floating performance
• Anti-rattle spring clips at each bobbin location for silent operation
• Swept groove surface treatment for enhanced pad bite and debris evacuation

Premium Materials and Construction:

• Outer friction rings cast from G3500 high-grade disc alloy with high carbon and high copper metallurgy for superior thermal conductivity and heat cycling durability
• Precision-machined bells crafted from aerospace-grade aluminum with hard anodized finish for excellent durability and appearance
• 48 directionally-handed curved vanes for maximum cooling efficiency
• Black heat-resistant coating on non-swept areas for corrosion protection

Race-Proven Performance:

• Tested to complete two full Reg 90 dynamometer test cycles with zero disc cracking—outperforming OE discs by over 4x in thermal fatigue testing
• Reduces unsprung rotational mass for improved handling, sharper turn-in, and better fuel economy
• Suitable for aggressive street driving, track days, and competitive motorsports
• Designed, manufactured, and run-out tested at EBC World Headquarters in Northampton, UK

Specifications:

• Rotor Diameter: 380mm
• Configuration: 2-piece fully-floating
• Surface: Swept Grooved
• Quantity: Sold as a pair (front axle set)
• Application: EBC Big Brake Kit replacement rotors only

These SG2FK-series rotors are specifically engineered for use with EBC Brakes Racing Big Brake Kits and should only be purchased as replacement components for existing EBC BBK systems. The advanced metallurgy and fully-floating design make these rotors ideal for enthusiasts who demand maximum braking performance with the reliability needed for both road and track use.
