SPL Parts Adjustable Front Caster Rod Monoball Bushings for G29 BMW Z4 and A90 / A91 Toyota Supra GR

SPL Parts’ FKS Series Adjustable Front Caster Rod Bushings (CRB) are designed to replace the stock flexible rubber bushings with low-friction, articulating spherical bearings, effectively eliminating bushing deflection and reducing friction. This ensures that the suspension geometry is maintained under load, enhancing braking and handling feedback. The bushings feature massive 1″ FK Racing Bearings with self-lubricating Teflon liners, ensuring maximum performance and durability. Additionally, the innovative CNC-machined offset bearing spacers allow for +/- 4 degrees of caster adjustment.
