SPL BMW G8X Rear Upper Arms

BMW G8X adjustable Rear Upper Arms (RUA) are an absolute necessity to maintain proper rear camber and reduce tire wear on the street and track. The stock BMW setup has an aggressive camber curve through bump travel, which is very apparent on lowered cars. Excess negative camber causes premature tire wear on the inside edge, and reduced traction on acceleration while too little camber will limit rear grip while cornering.  Our Rear Upper Arms provide a wide adjustment range for precise rear camber alignment that is easily optimized for street or track driving while eliminating bushing deflection with smooth articulating Teflon lined rod ends in place of the soft factory rubber bushings. Our kit replaces the factory links commonly referred to as the rear wishbone and rear guide links. BMW G8X Rear Upper Arms include gun drilled 2024 Aluminum traction links to reduce weight, as well as a 6061-T6 Billet Aluminum curved rear upper camber arm that are Black Anodized to prevent corrosion and
