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.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cem\u003e\u003cstrong\u003eBrake Rotor Specification: \u003c\/strong\u003e\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eOutside Diameter:\u003cstrong\u003e 350mm Ø\u003cbr\u003e\n\u003c\/strong\u003eDisc Thickness: \u003cstrong\u003e32mm\u003cbr\u003e\n\u003c\/strong\u003eDisc Construction:\u003cstrong\u003e 2-Peice floating\u003cbr\u003e\n\u003c\/strong\u003eDisc Vane Type: \u003cstrong\u003eCurved Vane\u003cbr\u003e\n\u003c\/strong\u003eMaterial: \u003cstrong\u003eCast Iron\u003c\/strong\u003e\u003cstrong\u003e\u003cbr\u003e\n\u003c\/strong\u003eBell PCD:\u003cstrong\u003e 350×32 D57 211mm x 8\u003cbr\u003e\n\u003c\/strong\u003eBell PCD: \u003cstrong\u003e350×32 D65 196mm x 8\u003cbr\u003e\n\u003c\/strong\u003eBell PCD: \u003cstrong\u003e350×32 D72 185mm x 8\u003cbr\u003e\n\u003c\/strong\u003eBell PCD:\u003cstrong\u003e 355×32 D54 223mm x 8\u003cbr\u003e\n\u003c\/strong\u003eBell PCD:\u003cstrong\u003e 355×32 D66 199mm x 8\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e________________________________________________________________\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eBRAKE PAD INFORMATION\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch6\u003e\u003cstrong\u003eSR21\u003c\/strong\u003e\u003c\/h6\u003e\n\u003ch6\u003eBC Sintered SR pads are in a class of their own.\u003c\/h6\u003e\n\u003ch6\u003eMade in the USA plant of EBC Brakes, SR bites harder and lasts longer than anything without damaging rotors.
