{"product_id":"billet-aluminum-rear-subframe-mount-insert-kit","title":"Billet Aluminum Rear Subframe Mount Insert Kit","description":"The 034Motorsport Billet Aluminum Rear Subframe Mount Insert Kit is engineered to enhance the driving dynamics of B9\/B9.5 Audi A4, S4, RS4, A5, S5, RS5, and Allroad models. The factory rubber rear subframe mounts are prone to deflection under load, leading to a vague and loose rear-end feel, suboptimal suspension geometry, and increased understeer. This kit addresses these issues by precisely filling the voids within the factory mounts.\n\nCrafted from T6-6061 billet aluminum and CNC-machined in-house, these inserts feature a clear anodized finish for superior durability. The design specifically targets the reduction of subframe movement during cornering, launches, and acceleration, which in turn helps maintain proper suspension geometry. This results in a more connected and responsive driving experience, with noticeable improvements in shifting feel for crisper gear changes. The manufacturer states that NVH (Noise, Vibration, Harshness) transfer to the cabin is minimal, rated as None to Low.\n\nThe kit includes front and rear billet aluminum inserts for both sides of the rear subframe. The original factory rear subframe bolts can be reused, with torque specifications provided in the installation guide. For those seeking new hardware, specific bolt part numbers (N91228001 and WHT004756A) are noted.\n\nThis kit is compatible with a wide range of B9\/B9.5 Audi vehicles, including A4, S4, RS4, A5, S5, RS5, and Allroad models from 2017 through the present, depending on specific trim and configuration. For example, it fits the 2017-Present Audi A4 (B9\/B9.5), 2017-Present Audi S4 (B9\/B9.5), 2017-Present Audi RS4 (B9\/B9.5), 2017-Present Audi Allroad (B9\/B9.5), 2018-Present Audi A5 (B9\/B9.5), 2017-Present Audi S5 (B9\/B9.5), and 2018-Present Audi RS5 (B9\/B9.5). Detailed fitment includes specific trims like Premium, Premium Plus, Prestige, and engine types such as 2.0L L4 and 3.0L V6.","brand":"034","offers":[{"title":"Default Title","offer_id":52686638645560,"sku":"034-601-0046","price":195.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687883171.webp?v=1784875535","url":"https:\/\/store.motormia.co\/products\/billet-aluminum-rear-subframe-mount-insert-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
