This upgrade maintains optimum suspension geometry under heavy braking and cornering loads, significantly improving handling feedback and braking stability.

These bushings utilize massive 1-inch FK Racing Bearings featuring self-lubricating Teflon liners to ensure maximum durability and consistent performance in both street and track environments. The innovative CNC machined offset bearing spacers allow for +/- 2 degrees of caster adjustment, giving you the ability to fine-tune your alignment beyond factory specifications.
