{"product_id":"380x36mm-mmx-carbon-ceramic-brake-rotor-conversion","title":"380x36mm MMX Carbon Ceramic Brake Rotor Conversion","description":"The MMX carbon ceramic brake rotor conversion is a high-performance upgrade for the BMW G87 M2, G80 M3, and G82\/G83 M4, specifically engineered for S58-powered vehicles equipped with factory iron brakes. By replacing stock steel rotors with this 380x36mm carbon ceramic set, drivers can reduce unsprung and rotating mass by 46%—or 6.9kg per disc—which improves steering response, turn-in sharpness, and overall ride compliance.\n\nFeaturing a 2-piece floating design, these rotors pair a carbon ceramic ring with an anodized black hat to accommodate radial and axial expansion during intense thermal cycles. The cross-drilled face effectively evacuates gas and pad debris, maintaining surface integrity under hard braking conditions that typically fade iron units.\n\nInstallation is a direct bolt-on process for factory iron-brake calipers and brackets, requiring no caliper swaps, bracket modifications, or system recalibration. Note that this kit is not compatible with vehicles that came from the factory with carbon ceramic brakes (CCB); it is exclusively for iron-to-CCB conversions. For optimal performance, it is recommended to pair these front rotors with the 370x24mm rear carbon ceramic rotors and Pagid RSL29 front brake pads.","brand":"MMR Performance","offers":[{"title":"Default Title","offer_id":52689254940984,"sku":"MMR30-1603F","price":7127.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687391648.webp?v=1784904134","url":"https:\/\/store.motormia.co\/products\/380x36mm-mmx-carbon-ceramic-brake-rotor-conversion","provider":"MOTORMIA","version":"1.0","type":"link"}
