EBC SG2FK-028 Racing Floating Brake Disc Rotors - 2-Piece 330mm Front Pair

The EBC SG2FK-028 Racing 2-Piece Floating Brake Disc assembly represents the pinnacle of EBC's brake rotor engineering, designed specifically as a replacement for EBC Racing Balanced Brake Kits. This complete assembly features 330mm front disc rings and is engineered for BMW 3-Series F30/F31/F34 chassis applications.

Premium Construction and Materials:

• Outer friction rings cast from high-copper, high-carbon G3500 disc alloy for superior thermal conductivity
• Precision-machined aerospace-grade aluminum bells with hard anodizing for durability and appearance
• All bobbins machined from a single piece of stainless steel to prevent corrosion and ensure free floating operation
• Features 48 directionally-handed, curved vanes that efficiently dissipate heat and delay brake fade
• Designed, manufactured, and run-out tested in the UK

Advanced SD-Drive Technology:

• Patented SD-Drive technology bobbins allow up to 3mm of expansion and contraction under extreme braking heat
• Anti-rattle spring clips at each bobbin location ensure silent operation without off-brake disc rattle
• Seamlessly converts 2-piece pin-drive discs to fully floating systems without vehicle modifications

Performance Benefits:

• Reduces unsprung rotational mass for sharper turn-in, improved tire road holding, better fuel economy, and increased horsepower at the wheels
• Lighter than OE discs while engineered for superior performance
• Low maintenance solution suitable for both public roads and race track use

Cost-Effective Long-Term Solution:

When the cast iron friction ring wears out, it can be replaced independently, allowing the center hub and stainless bobbins to be reused, significantly reducing long-term operating costs. This complete assembly pair is sold as a direct replacement for existing EBC Racing Big Brake Kit installations.
