SGDR340x30 D66LH - EBC Replacement Disc - 340x30mm Slotted Left

EBC’s 2-piece replacement discs have been tested to withstand hundreds of hours the harshest track driving. All cast iron rings feature 48 curved vanes and are handed left and right, ensuring the vanes always rotate in the correct direction, giving maximum cooling efficiency. All outer friction rings are cast from a high-copper, high-carbon G3500 disc alloy giving them a high resistance to wear and cracking, even when used on track or for racing. The cast iron outer ring ‘floats’ on EBC's patented SD-Drive technology bobbins, allowing the friction ring to expand and contract freely by up to 3mm when subjected to the extreme heat generated from hard braking. All bobbins are machined from a single piece of stainless steel, preventing unsightly corrosion and ensuring the outer ring continues to float freely, even after years of exposure to road elements. Each bobbin location also features an anti-rattle spring clip, meaning these discs are totally silent in operation.
