EBC SGDR340X30 D66LH Racing Replacement Disc Ring 340mm Left

The EBC SGDR340X30 D66LH is a high-performance replacement disc ring designed for 340x30mm 2-piece fully-floating brake rotor systems. This front left replacement ring features 48 directionally curved vanes and a swept groove finish, engineered specifically for racing and high-performance track applications.

Advanced G3500 Disc Alloy Construction:

Each outer ring is cast from the highest-grade disc alloy 'G3500', derived from race technology with high carbon and high copper metallurgy for superior thermal conductivity and heat cycling durability. This premium G3500 alloy offers high resistance to wear and cracking, even when used on track or for racing.

Key Features:

• 340mm diameter with 30mm new thickness and 28mm minimum thickness
• 48 curved vanes handed for left side installation, ensuring vanes rotate in the correct direction for maximum cooling efficiency
• Floats on EBC's patented SD-Drive technology bobbins, allowing the friction ring to expand and contract freely by up to 3mm under extreme braking heat
• Comes complete with new hardware and full instructions for re-assembly
• Stainless steel bobbins machined from a single piece prevent corrosion and ensure free floating action after years of exposure
• Anti-rattle spring clips at each bobbin location for totally silent operation

EBC's 2-piece replacement discs have been tested to withstand hundreds of hours of the harshest track driving, making this an ideal replacement component for maintaining peak braking performance in demanding motorsports applications.
