SPL Parts BMW F8X Adjustable Rear Upper Control Arms for M2, M3, M4

Description

The SPL Parts BMW F8X adjustable rear upper control arms are engineered to optimize rear camber alignment, enhancing tire longevity and vehicle performance on both street and track. Designed specifically for 2015-2018 BMW M2, M3, and M4 models, these arms replace the stock factory links—commonly known as rear wishbones and guide links—providing a more precise and durable solution for suspension tuning. Built from lightweight 2024 aluminum and finished with a corrosion-resistant black anodized coating, these arms not only reduce unsprung weight but also offer long-lasting durability.
Featuring a 360-degree 6061-T6 aluminum rotating clamp, these control arms enable quick and accurate camber adjustments without the need for complex tools or multiple wrench turns. The clamps are secured with blue anodized titanium socket head cap screws, allowing for effortless access and fine-tuning while maintaining structural integrity. The high-quality FK spherical bearings and rod ends utilize Teflon liners for quiet operation, lower friction, and smooth articulation, effectively eliminating bushing deflection under load. This results in improved rear grip, consistent camber settings, and enhanced handling characteristics.
Installation of these adjustable arms is straightforward and includes a complete set for one vehicle, ensuring a comprehensive upgrade. Proudly manufactured, engineered, and assembled in the USA, SPL Parts integrates premium materials and design features that deliver superior performance, durability, and ease of adjustment. Whether for street driving or aggressive track use, these rear upper control arms are essential for maintaining optimal suspension geometry and maximizing vehicle control.
