This eLINE Black Series rotor combines a performance-focused cross-drilled braking surface with a black zinc finish designed to help protect exposed non-friction areas from corrosion while delivering a clean, aggressive appearance. Precision-drilled and countersunk openings are designed to promote heat dissipation during repeated braking, making this rotor a strong street-performance replacement for drivers who want both function and style.

Precision-drilled openings help promote heat dissipation during repeated braking, while countersunk hole edges are engineered to reduce stress concentration around the drilled surfaces. Built around application-specific replacement dimensions, the eLINE Black Drilled series offers a performance-focused rotor option for street-driven cars, trucks and SUVs.\u003c\/p\u003e\u003cp\u003eThe rotor arrives with a full black zinc finish. During proper bedding, the coating on the brake-pad contact surface naturally wears away to expose the metallic friction surface while the black finish remains on protected non-contact areas such as the rotor hat. Rotor construction, dimensions and fitment vary by application, so axle position and left\/right orientation should always be matched to the individual manufacturer part number.\u003c\/p\u003e","brand":"R1 Concepts","offers":[{"title":"Default Title","offer_id":55398635274408,"sku":"RNC623-48005L","price":72.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0496\/1016\/2344\/files\/6b4e002d9f07c2dd7ac0bfb798020d37L_eb27e567-84ab-4afb-9d92-7091ade48437.jpg?v=1776553072","url":"https:\/\/eliteracefab.com\/products\/r1-623-48005l","provider":"eliteracefab.com","version":"1.0","type":"link"}
