SHW is the BMW OEM supplier for this assembly; the unit supplied here is produced to the identical specification as the factory-installed disc. Aftermarket alternatives frequently present dimensional deviations in the floating contact points between hat and ring, introducing thermal distortion and vibration under sustained high-temperature braking. This factory-specification right rotor ensures correct floating motion, hat parallelism, and thermal expansion characteristics matched to the M5\/M8 front caliper geometry.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation Note\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReplace front rotors as an axle pair — never single side. Use new rotor retention bolt — cannot be reused. Torque to BMW specification. Bed new rotors per BMW M procedure before full-load braking. Inspect caliper slides and pad condition before installation.\u003c\/p\u003e","brand":"BMW","offers":[{"title":"Default Title","offer_id":52221144170786,"sku":"BMW-34117991102-R","price":898.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0944\/3957\/1746\/files\/066-37_2_bdf5ad08-6019-4d57-9aeb-8e7ce470cd6a.webp?v=1786016068","url":"https:\/\/europarts360.com\/fr\/products\/bmw-m5-m8-front-brake-rotor-right-oem-34117991102","provider":"Europarts360","version":"1.0","type":"link"}
