{"product_id":"e46-rear-subframe-chassis-reinforcement-kit","title":"E46 Rear Subframe\/Chassis Reinforcement Kit","description":"The BimmerWorld E46 Rear Subframe\/Chassis Reinforcement Kit is engineered to solve the prevalent issue of rear subframe mounting points ripping away from the unibody, a problem that also affected earlier E36 models. Developed in-house by BimmerWorld, this expanded kit offers greater surface area and coverage of problem areas compared to previous designs.\n\nThis reinforcement kit is crucial for any E46 driven hard, especially those used for autocross, track days, or racing. It proactively protects the subframe and chassis from potentially costly damage. The kit includes four main subframe mounting point reinforcements, spacers to realign the cross member, necessary hardware, and plates for the trunk's access panels. It is constructed from steel and made in the USA.\n\nInstallation requires welding and is recommended to be performed by an experienced, professional shop. BimmerWorld also strongly advises replacing worn rubber subframe bushings with polyurethane or solid aluminum mounts during this installation. The company recommends Powerflex polyurethane (Street 70A or Black Series 95A) for street use and solid aluminum for dedicated track and race vehicles. New, stiffer mounts will further enhance chassis integrity by ensuring the subframe remains secure.\n\nThis reinforcement kit fits all BMW E46 models, including the M3. Specific BMW Fitments include: 3 Series E46 (99-00) \u0026gt; 323i, E46 (99-00) \u0026gt; 323ci, E46 (01-05) \u0026gt; 325i, E46 (01-06) \u0026gt; 325ci, E46 (01-05) \u0026gt; 325xi, E46 (99-00) \u0026gt; 328i, E46 (99-00) \u0026gt; 328ci, E46 (01-05) \u0026gt; 330i, E46 (01-06) \u0026gt; 330ci, E46 (01-05) \u0026gt; 330xi, and E46 (01-06) \u0026gt; M3.","brand":"BimmerWorld","offers":[{"title":"Default Title","offer_id":52687170371896,"sku":"100.33.546.0005B","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660187736.jpg?v=1784881045","url":"https:\/\/store.motormia.co\/products\/e46-rear-subframe-chassis-reinforcement-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
