{"product_id":"carbon-fiber-doors","title":"Carbon Fiber Doors","description":"The Karbonius E92 M3 Coupe Carbon Door Set provides a substantial weight reduction for the BMW E92 M3 Coupe (S65 engine), saving approximately 13 kg per door over the stock steel components. This upgrade is more than a cosmetic enhancement; Karbonius manufactures these doors as structural safety items. The exterior panels and integrated side-impact protection bars are crafted from 100% prepreg carbon fiber and Aramid fiber (Kevlar) prepreg, ensuring maximum strength with minimal weight.\n\nThe integrated Kevlar side-impact protection bars are bonded within the door shell using structural adhesive and secured with OEM-spec hardware. Precision robot-cut openings for the interior panels allow all OEM mechanisms, including window regulators, locks, rubbers, and trim, to be installed and operate correctly.\n\nEach Karbonius door is individually numbered for authenticity and manufactured in Spain under ISO 9001 quality management standards. The standard finish is primed and ready for painting, with other finish options available upon request. A 2-Year manufacturer warranty is included. Please note that interior panels, window regulators, rubbers, locks, and OEM trim are not included and must be transferred from the original doors. Professional installation is recommended due to the structural nature of these components, requiring qualified fitment.","brand":"Karbonius","offers":[{"title":"Default Title","offer_id":52662800580920,"sku":"E92D01-PRM-CF-4","price":5499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687498639.webp?v=1784321127","url":"https:\/\/store.motormia.co\/products\/carbon-fiber-doors","provider":"MOTORMIA","version":"1.0","type":"link"}
