Overview

These arms feature 7075-T6 aluminum construction and heat-treated steel rod ends to provide greater strength and adjustability than factory components.
Show original supplier description
The NM Engineering Adjustable Control Arm Kit replaces factory rear arms with a more rigid and adjustable solution suitable for both street driving and track competition. Constructed from aerospace-grade 7075-T6 aluminum in a 1-1/4” hex bar design, these arms offer high stiffness with significant weight reduction. Each arm is treated with a titanium-tint Type III / Mil-Spec anodized finish to ensure long-term corrosion resistance and surface durability. Included T-303 stainless steel spacers prevent mounting-point deformation, while the fully threaded design allows for precise camber and toe tuning. Installation of this kit is simplified as the arms arrive pre-set to factory lengths. Note that the use of a heim joint (pillow-ball rod end) design may introduce slight additional noise compared to rubber bushings. For vehicles equipped with HID (Xenon) headlights, fitment is strictly limited to replacing lower control arms only. Additionally, an optional dust boot is recommended to protect the rod ends from debris and further extend service life. This kit is compatible with specific F-Chassis models, including BMW F39, F44, and F48, as well as MINI F54, F55, F56, F57, and F60. Please verify your vehicle configuration before installation to ensure proper fitment of the lower control arm components.
