Product Details
At the heart of the system are offset performance synthetic elastomer bushings on your 2015-2018 BMW M3 (F80), 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 home on a fast road car or a dedicated track setup.
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.
The Whiteline KTA285 front tension strut arm upgrade is a purpose-built solution for drivers who want sharper braking response, improved turn-in, and added front-end adjustability without sacrificing street manners. 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.
