SPL Parts Front Lower Control Arms - BMW M340i/M440i (G20/G22)

OVERVIEW

SPL BMW G2X Front Lower Control Arms (FLCA) provide roll-center, camber, and track-width adjustment for the M340i and M440i while eliminating the bushing deflection that dulls steering response. Running more negative camber and a slightly wider track width meaningfully improves peak lateral grip — especially with stickier tires, and a must-have for anyone fighting excessive outer-shoulder tire wear from insufficient factory camber.

SPECS

• Lightweight 6061-T6 billet aluminum arm with titanium hardware
• Electroless nickel-plated 4130 chromoly Double Adjuster for quick, repeatable adjustment

• Low-friction 3-piece Teflon-lined FK sphericals and rod ends
• Includes a ride-height sensor bracket to maintain the factory sensor location regardless of arm length
• Suitable for daily driver to full race car use
• Made in the USA
