Designed to address the significant loads placed on the front tension strut (also known as the thrust arm) under braking and corner entry, this upgrade delivers tangible performance gains where it matters most.  Factory rubber bushings are intentionally soft and open in design to allow multi-axis movement during steering, but under heavy braking they compress and release, allowing unwanted arm deflection. The result is reduced stability, inconsistent braking feel, and tire skip—issues that are amplified when ABS is engaged or the car is driven hard. Whiteline's upgraded arm and bushing solution dramatically reduces this compliance, keeping the suspension geometry stable and the tire planted under load.  At the heart of the system are offset performance synthetic elastomer bushings, which increase caster and camber for improved straight-line stability, enhanced steering feel, and stronger front-end grip on corner entry. This added adjustability allows enthusiasts to dial in a more aggressive alignment without the need for additional hardware, making it equally at h(more...)\u003ch6\u003eVehicle Fitment\u003c\/h6\u003e \u003ctable style=\"width: 100%; border-collapse: collapse; font-family: Arial, sans-serif; font-size: 14px;\"\u003e \u003ctbody\u003e \u003ctr style=\"background-color: #f2f2f2;\"\u003e \u003cth style=\"border: 1px solid #ddd; padding: 8px; text-align: left;\"\u003eManufacturer\u003c\/th\u003e \u003cth style=\"border: 1px solid #ddd; padding: 8px; text-align: left;\"\u003eModel\u003c\/th\u003e \u003cth style=\"border: 1px solid #ddd; padding: 8px; text-align: left;\"\u003eYear\/Chassis Group\u003c\/th\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd style=\"border: 1px solid #ddd; padding: 8px;\"\u003eBMW\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 8px;\"\u003e2\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 8px;\"\u003e2013-2021 | 2 SERIES F87 M2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 8px;\"\u003eBMW\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 8px;\"\u003e3\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 8px;\"\u003e2014-2019 | 3 SERIES F30F80 M3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 8px;\"\u003eBMW\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 8px;\"\u003e4\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 8px;\"\u003e2014-2020 | 4 SERIES F82F83 M4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch6\u003eProduct Details\u003c\/h6\u003e\n\n\u003cdiv\u003e\n\u003cb\u003eBrand: \u003c\/b\u003eWhiteline Performance\u003c\/div\u003e\n\n\n \n\u003cdiv\u003e\n\u003cb\u003eManufacturer Part Number: \u003c\/b\u003eKTA285\u003c\/div\u003e\n\n\n\n\u003cstrong\u003eOE \/ OEM Reference:\u003c\/strong\u003e\nKTA285\n, 1063681909\n, 9.32E+12\n\n\n\n\n\n\n\n\n\u003cdiv\u003e\n\u003cb\u003eChassisGroupID: \u003c\/b\u003e1063681909\u003c\/div\u003e\n\n\n\n\u003cdiv\u003e\n\u003cb\u003eItem Barcode: \u003c\/b\u003e9.32E+12\u003c\/div\u003e\n\n\n\n\n\n\u003cdiv\u003e\n\u003cb\u003eType: \u003c\/b\u003eControl Arm\u003c\/div\u003e\n\n\n\n\u003cdiv\u003e\n\u003cb\u003eAxle: \u003c\/b\u003eFront Axle\u003c\/div\u003e\n\n\n\n\u003cdiv\u003e\n\u003cb\u003ePosition: \u003c\/b\u003eFront Axle;Lower;both sides\u003c\/div\u003e\n\n\n\n\u003cdiv\u003e\n\u003cb\u003ePA Note: \u003c\/b\u003ePerformance - adds +\/-0.5deg caster - includes ball joint\u003c\/div\u003e\n\n\n\n\u003cdiv\u003e\n\u003cb\u003ePAFootNote1: \u003c\/b\u003ePerformance\u003c\/div\u003e\n\n\n\n\u003cdiv\u003e\n\u003cb\u003ePAFootNote2: \u003c\/b\u003eAdds +\/-0.5deg caster\u003c\/div\u003e\n\n\n\n\u003cdiv\u003e\n\u003cb\u003ePAFootNote3: \u003c\/b\u003eIncludes ball joint\u003c\/div\u003e\n\n\n\n\u003cdiv\u003e\n\u003cb\u003eProductFootNote1: \u003c\/b\u003ePerformance arm\u003c\/div\u003e\n\n\n\n\n","brand":"Whiteline Performance","offers":[{"title":"Default Title","offer_id":56364661440891,"sku":"WHI-KTA285","price":508.64,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0511\/6700\/2795\/files\/809dc859-738d-42ee-a393-798480192265.jpg?v=1785836971","url":"https:\/\/hazmotorsport.co.uk\/products\/whiteline-suspension-front-tension-strut-arm-bmw-2-3-4-2013-2021-kta285","provider":"HAZ MOTORSPORT","version":"1.0","type":"link"}
