SPL Parts BMW F8X M2 M3 M4 Adjustable Front Lower Control Arms (FLCA) - Camber & Track Width Adjustment, Roll Centre Correction (F80 F82 F83 F87)

SPL FLCA Adjustable Front Wishbone Kit for BMW F8x M2, M3, M4

Transform steering response and alignment adjustability on your F8x chassis with SPL’s adjustable front wishbones. This premium lower A arm set gives you the fine control needed to dial in extra negative camber and a wider front stance while restoring suspension geometry on lowered cars. Expect razor sharp turn in, improved tyre contact across the tread and a front end that feels planted on fast road and track.

Engineered for serious use, the arms combine 6061-T6 billet aluminium bodies, blue anodised titanium fasteners and a gun drilled 4130 chromoly centre adjuster that is electroless nickel plated for corrosion resistance. PTFE lined FK rod ends and high misalignment spherical bearings replace soft factory rubber, removing flex and binding for consistent handling and precise feedback. Multiple stainless spacers let you correct roll centre and maintain the proper ball joint angle for full articulation.

On-car adjustment is quick and repeatable thanks to SPL’s clever double adjuster and rotating clamp system. No jam nuts, no fuss. Make changes in minutes, lock them down securely and head straight back out.

We run these on our own builds and customer cars. Feedback is the same every time — more grip, cleaner tyre wear and an alignment that stays where you set it.
