      SPL Parts 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.

      SPL Parts Rear Upper Arms are gun drilled 2024 Aluminum links to reduce weight, then are Black Anodized to prevent corrosion and provide a durable finish. Our exclusive 360 degree 6061-T6 Aluminum Rotating Clamp design allows for quick, precise adjustment. Our Clamps tightened down with Blue Anodized Titanium Socket Head Cap Screws gives easy access to adjust camber settings, shaving off even more unsprung weight without compromising strength. Our Rear Upper Links provide superior performance, durability, and ease of adjustment. Long gone are the days of fumbling with wrenches to tighten jam nuts while trying to trying to keep your bearings oriented correctly.

      FK Spherical Bearings and Rod Ends are manufactured in Connecticut and utilize a Teflon liner to provide quiet operation, lower friction, smooth articulation, and eliminates bushing deflection under load. The liner is also self-lubricating and self-cleaning, offering robust reliability for street and track use. The PTFE liner is chemically bonded to the inner diameter of the race, and offers a very high load carrying capacity that has greatly increased dynamic wear characteristics. The operating temperature of the liner ranges from -65º to 325ºF, offering robust reliability.

      Sold as a complete kit for one car (4 total arms).

      Made in the USA.
