Unlike solid rear discs found on smaller models, these are internally vented to dissipate heat more effectively during high-speed braking or when the vehicle is under heavy load.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eThe G30 5 Series utilizes a \"two-piece\" lightweight design featuring a high-carbon cast iron friction ring pinned to an aluminium hat (hub). This construction reduces unsprung weight, improving both handling and ride comfort. Over time, these discs will develop a \"lip\" on the outer edge or may suffer from thickness variation (warping), leading to steering wheel vibration or a pulsating brake pedal. Because the G30 uses an Electronic Parking Brake (EPB), the rear discs must be replaced with the parking brake in \"Service Mode\" to retract the calipers safely. It is highly recommended to replace these in pairs across the axle to ensure balanced braking performance.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003e\u003cb data-path-to-node=\"3\" data-index-in-node=\"0\"\u003eVehicle Compatibility:\u003c\/b\u003e \u003c\/p\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,0,0\"\u003e\u003cb data-path-to-node=\"4,0,0\" data-index-in-node=\"0\"\u003e3 Series (G20):\u003c\/b\u003e 2017–2023\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul data-processed=\"true\" data-complete=\"true\" data-sfc-cb=\"\" data-sfc-root=\"c\" class=\"KsbFXc U6u95\"\u003e\n\u003cli data-sae=\"\" data-complete=\"true\" data-hveid=\"CAEIBxAB\" data-sfc-cb=\"\" data-sfc-root=\"c\" class=\"dF3vjf\"\u003e\u003cspan aria-owns=\"action-menu-parent-container\" data-complete=\"true\" data-sfc-cb=\"\" data-sfc-root=\"c\" data-sfc-cp=\"\" class=\"T286Pc\"\u003e\u003cstrong data-complete=\"true\" data-sfc-cb=\"\" data-sfc-root=\"c\" class=\"Yjhzub\"\u003e4 Series (G22):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e430i, 430i xDrive.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,1,0\"\u003e\u003cb data-path-to-node=\"4,1,0\" data-index-in-node=\"0\"\u003e5 Series (G30):\u003c\/b\u003e 2017–2023\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eX3(G01)\u003c\/strong\u003e: 2017–2025\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eX4(G02)\u003c\/strong\u003e: 2017–2025\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"6,1,0\"\u003ePosition:\u003c\/b\u003e Rear Axle (Left or Right)\u003c\/p\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"6,2,0\"\u003eType:\u003c\/b\u003e Vented \/ Two-Piece Lightweight\u003c\/p\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"6,3,0\"\u003eDiameter:\u003c\/b\u003e 345mm\u003c\/p\u003e\n\u003cp data-path-to-node=\"6,4,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"6,4,0\"\u003eThickness:\u003c\/b\u003e 24mm (Minimum allowable: 22.4mm)\u003c\/p\u003e","brand":"BMW","offers":[{"title":"Default Title","offer_id":48194726363375,"sku":"34216882246","price":1950.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/7183\/5631\/files\/2018-G30-5Series-Rear-Brake-Disc_3.png?v=1774367862","url":"https:\/\/myty.co.za\/products\/rear-brake-disc-vented-bmw-3-4-5-series-x3-x4-x5-2013-2025","provider":"MYTY Auto Parts","version":"1.0","type":"link"}
