{"product_id":"thrust-arm-monoball-upgrade","title":"Thrust Arm Monoball Upgrade","description":"Stock rubber bushings allow for significant fore\/aft wheel movement and are fluid-filled for comfort, but this design can lead to a disconnected steering feel, premature failure, and issues like wheel shimmy, delayed response, and poor tire wear.\n\nThis upgrade utilizes a sealed OEM BMW ball joint for durability, housed within a precision CNC-machined 6061-T6 anodized aluminum assembly. The housing features a knurled outer diameter for a secure press fit and is mated with CNC-machined 304ss components to ensure a precise fit between the ball joint and subframe. This design eliminates unwanted deflection and friction, providing exceptional steering precision, crisp turn-in, and direct braking feedback.\n\nThe Turner Thrust Arm Monoball Upgrade is maintenance-free and offers long-lasting performance. It's suitable for track cars and enthusiasts who enjoy spirited driving, offering improved road feel without undesirable NVH (Noise, Vibration, Harshness).\n\nFitment includes BMW M2 (2016-2018 Base, 2020 CS, 2019-2021 Competition), M3 (2015-2018 Base Sedan), and M4 (2015-2020 Base Convertible and Coupe, 2019-2020 CS, 2016 GTS Coupe).","brand":"Turner Motorsport","offers":[{"title":"Default Title","offer_id":52689477665080,"sku":"023671TMS01","price":371.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687752599.jpg?v=1784906954","url":"https:\/\/store.motormia.co\/products\/thrust-arm-monoball-upgrade","provider":"MOTORMIA","version":"1.0","type":"link"}
