As part of EBC's GD Series, these rotors feature a slotted and dimpled surface designed to enhance braking consistency, improve heat management, and reduce brake fade under spirited driving conditions.\u003c\/p\u003e\u003cp\u003eThe slot pattern continuously clears dust, gases, and debris from the brake pad surface, ensuring strong and consistent pad contact. The dimpled design helps reduce thermal stress compared to fully drilled rotors, improving durability while maintaining effective heat dissipation.\u003c\/p\u003e\u003cp\u003eManufactured from OE-grade cast iron with a corrosion-resistant Geomet coating, the GD1647 provides long service life and stable braking performance. It is intended as a direct replacement upgrade for OEM rear sport brake systems and must be matched to the correct 324-325 mm configuration for proper fitment and safety.\u003c\/p\u003e","brand":"EBC","offers":[{"title":"Default Title","offer_id":50500579000639,"sku":"EBCGD1647","price":314.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/5145d9a137fa5e08c60e21e5e772b5a7L_8a8b6ea4-b064-429f-8219-ebb3f91f6542.jpg?v=1741652470","url":"https:\/\/wcaperformance.com\/products\/ebc-08-10-bmw-135-3-0-twin-turbo-gd-sport-rear-rotors","provider":"WCA Performance","version":"1.0","type":"link"}
