SPL Parts Adjustable Spherical Caster Rod Bushings for BMW M3 M4 (G8X)

Improve braking stability and steering feedback on your track driven BMW with SPL Parts Adjustable Spherical Caster Rod Bushings. The factory rubber bushings flex under hard braking and cornering loads, causing dynamic alignment changes that lead to inconsistent handling. These performance bushings replace the stock rubber with low friction, articulating spherical bearings to eliminate deflection, keeping your suspension geometry stable when you need it most. They provide up to plus or minus 2 degrees of caster adjustment to optimize your alignment setup.Vehicle FitmentThis product fits the 2021 to 2026 BMW M3 (G80) and BMW M4 (G82 and G83).
