SPL Parts Titanium Series Adjustable Rear Toe Links/Arms (RTA F3X) for BMW F2X/F3X 2/3/4 Series Aluminium, FK Bearings Pair, Made in USA

BMW F2X F3X Rear Toe Control Rods by SPL Parts

Dial in your rear-end geometry with SPL Parts Titanium Series rear toe control rods for BMW F2X and F3X platforms. This premium suspension upgrade gives you laser-accurate toe correction, rock-solid stability and sharper cornering feel by replacing the flexible factory arms with rigid, motorsport-grade components. Ideal for fast road, track days and drift alignment, these precision links help maximise grip and reduce uneven tyre wear on 2 Series, 3 Series and 4 Series models.

Built around gun-drilled 2024 aluminium tie rods to cut unsprung mass, each arm uses a 6061-T6 rotating clamp for quick, repeatable on-car adjustment. Blue anodised titanium socket head cap screws keep everything locked with minimal weight. At each end, high quality FK PTFE lined spherical bearings and rod ends deliver smooth articulation with no slop, no bind and no rubber deflection. The result is consistent alignment under load, improved rear axle composure and a more connected drive.
