Product Details

Megan Racing Rear Upper Control Arms for the 2018–2024 BMW 8 Series (G14) provide the adjustment range needed to correct rear camber when lowering or modifying your car. Factory arms leave little room for adjustment, often resulting in excessive negative camber, uneven tire wear, and compromised handling. These adjustable rear control arms (often referred to as camber arms) allow precise correction to restore proper alignment geometry for street or track use.

Constructed from lightweight CNC-machined aluminum and anodized in gunmetal for corrosion resistance, these arms combine strength and style. Turnbuckle adjustability with reverse threads makes on-car adjustments quick and accurate, while spherical bushings replace soft OEM rubber to eliminate deflection and sharpen suspension response. All hardware is corrosion-treated, and the arms are backed by a 1-year manufacturer warranty.
