EBC SG2FC1877 Fully-Floating 2-Piece Front Brake Rotors 340x30mm Slotted

The EBC SG2FC1877 is a premium 2-piece fully-floating brake rotor designed to deliver the highest quality braking performance available on the market. These rotors measure 340mm in diameter with a 30mm thickness and are sold as a pair for front axle applications.

Advanced Construction:

• Outer friction rings cast from high-copper, high-carbon G3500 disc alloy for exceptional resistance to wear and cracking
• Precision-machined aerospace-grade aluminum bells with hard anodized finish for durability and great looks
• 48 directionally-curved vanes that are handed left and right for maximum heat dissipation and cooling efficiency
• Swept groove (SG) pattern that increases resistance to cracking and allows gases to escape, preventing brake fade

Patented SD-Drive Technology:

• Cast iron outer ring floats on patented SD-Drive bobbins, allowing the friction ring to expand and contract freely by up to 3mm under extreme heat
• All bobbins machined from single-piece stainless steel that will never rust
• Anti-rattle spring clips at each bobbin location ensure totally silent operation without off-brake disc rattle

Performance Benefits:

• Lightweight aluminum hub design reduces overall weight to just 18.9kg (41.7 lbs) per pair
• Reduces un-sprung rotational mass for noticeable improvements in corner entry turn-in, tire road holding, and fuel economy
• Direct bolt-on upgrade requiring no vehicle modifications
• Replaceable outer rings allow for cost-effective long-term maintenance—only the friction ring needs replacement when worn

These UK-designed, manufactured, and run-out tested rotors offer a low-maintenance solution suitable for both public roads and race track use. EBC Racing has extensively track-tested this design to ensure it meets exacting standards and can withstand the most demanding driving conditions.
