The SPL Rear Traction Arms provide the necessary adjustability to the anti-squat to improve mechanical grip and adjust the rear kinematics to suit your build. Larger PTFE-lined, F1-fit FK USA spherical bushings provide the benefits of the OEM spherical with longer life due to the increased surface area of the bearing. The kit allows for a deeper customization of the suspension geometry to better suit your driving preferences and adapt to changes in tracks, aero loading, tires, and more.
