Product Description

The Whiteline **KTA383** is a premium front lower control and radius arm upgrade designed specifically for BMW 2-Series, 3-Series, and 4-Series vehicles (F-platforms), excluding M-models. This complete 4-arm set replaces factory rubber arms with adjustable alloy components featuring synthetic elastomer bushings. They enable fine-tuning of camber (±0.5°) and caster (up to +0.8°), offering sharper steering response, improved tyre wear characteristics, and greater chassis control.

These bolt-on assemblies require no pressing of bushings, simplifying installation and minimizing downtime. Internal lubrication reservoirs and low-compliance bushings maintain performance longevity while limiting NVH. With a fixed +1.0° camber and adjustable caster, they help restore proper alignment after lowering, improving handling and stability under acceleration, braking, and cornering.

This kit is ideal for enthusiasts or drivers who demand precise alignment control, reduced dynamic deflection, and improved grip on lowered or track-prepped BMW F-platform cars. Warranty coverage is 3-years or 60,000 mi (~100,000 km). Coverage confirmed through model year **2021**; fitment for 2022-2025 remains unconfirmed at time of listing. A 4-wheel alignment after installation is essential.
