At 350mm in diameter, it is the larger of the two front rotor sizes used on the W164\/X164 platform, fitting GL450, GL550, GL320 CDI, GL350 BlueTEC, ML550, and 7-passenger R350 variants. It directly replaces Mercedes-Benz OE part numbers 1644210512 and 1644211412, ensuring a confirmed bolt-on fit without modification.\u003c\/p\u003e\u003cp\u003eBuilt from high-carbon cast iron with an internally vented design, this rotor handles the thermal demands of heavy SUV braking effectively, resisting fade under sustained use. The full UV coating - applied using a solvent-free, low-energy process - protects the entire rotor surface including internal vents, providing corrosion resistance that exceeds OE standards. Each rotor is ECE R-90 certified and electronically balanced at the factory. Sold individually; two rotors are required to complete a front axle service.\u003c\/p\u003e","brand":"Brembo OE","offers":[{"title":"Default Title","offer_id":53198165377343,"sku":"BRE09.R103.11","price":94.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/5b1d48b778196c253e90e1eb9968164e_c0baa718-5b4b-4350-85da-5ad0857a0bf8.jpg?v=1779934487","url":"https:\/\/wcaperformance.com\/products\/brembo-07-08-mercedes-benz-gl320-10-12-gl350-front-premium-uv-coated-oe-equivalent-rotor","provider":"WCA Performance","version":"1.0","type":"link"}
