SPL BMW M3 & M4 (14+) Titanium Rear Upper Arms

SPL Titanium Series Adjustable Rear Upper Arms BMW F8X M3 M4

SPL adjustable links 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.  SPL links 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.

Our links feature black anodized and gundrilled 2024 aluminum links, 6061 aluminum clamps, titanium socket head cap screws, tapered stainless steel knuckle mount spacers and FK rod ends. This combination provides 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 orientated correctly.
