This design helps maintain consistent brake pad contact and reduces brake fade under demanding conditions. The zinc silver hat finish provides corrosion resistance, extending rotor life, especially in environments prone to rust.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow better airflow and heat dissipation, which is critical for maintaining braking performance during extended use. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, indicating when replacement is necessary. The rotor measures 300 mm in outside diameter and 76.2 mm in overall height, fitting precisely on BMW 125i and 128i models. The 5 bolt holes, each 14.5 mm in diameter, are arranged on a 120 mm bolt circle diameter, ensuring proper fitment. The directional slotted and drilled surface enhances braking by channeling away debris and heat, while the zinc silver hat finish with rust-resistant coating protects against corrosion.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eImproves braking performance for BMW 125i and 128i vehicles\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during high-temperature conditions\u003c\/li\u003e\n\u003cli\u003eHelps prevent rust and corrosion on the rotor surface\u003c\/li\u003e\n\u003cli\u003eEnhances water and gas evacuation for consistent brake pad contact\u003c\/li\u003e\n\u003cli\u003eMaintains structural integrity with vented design for heat dissipation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed on compatible BMW 125i or 128i models matching the 5-lug, 120 mm bolt circle pattern. Verify the rotor thickness before installation; replace if below the discard thickness of 18.4 mm. Clean the rotor surface to remove any protective coatings or debris before mounting. Proper torque specifications should be followed for the 14.5 mm bolt holes to ensure secure fitment and optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-31088R rotor to meet OEM standards for fit and function. The rust-resistant zinc silver hat finish extends rotor life by protecting against corrosion. While no specific warranty information is provided, the product is designed to maintain consistent braking performance and durability when installed and maintained according to manufacturer guidelines.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51794115821749,"sku":"HBHR-631-31088R","price":93.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63131088R_Fro.jpg?v=1774641369","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-31088r-disc-brake-rotor-rear-right","provider":"PartCatalog","version":"1.0","type":"link"}
