Product Description

The SPL Parts SPL FLCA G8X Adjustable Front Lower Control Arms are precision-engineered suspension components designed specifically for *BMW G8X* RWD M3 and M4 models from 2021 through 2026. These upgrade arms allow enthusiasts and tuners to fine-tune camber, track width, and roll center settings to match performance driving needs. Unlike stock arms, the SPL design eliminates bushing deflection, giving drivers sharper steering response, better cornering precision, and improved tire contact patch under load.

Constructed from lightweight 6061-T6 billet aluminum with premium FK PTFE-lined spherical bearings and machined chromoly Double Adjusters, the SPL FLCA G8X arms are built for strength without excess weight. The unique rotating clamp design makes locking alignment settings easier and more reliable than traditional jam-nut setups. Stainless steel roll center spacers are included to retain proper geometry when the vehicle is lowered, and a ride height sensor bracket ensures factory electronics remain functional regardless of arm length. These arms are sold as a pair and represent a substantial handling upgrade for RWD BMW M3/M4 G8X owners seeking optimized suspension control on street or track.
