• Function: This bolt features an eccentric cam design that enables fine adjustment of suspension geometry. It’s critical for setting camber and toe angles, ensuring your Porsche tracks straight and maintains optimal tire contact for cornering grip and stability.
• Why Replacement Matters: Over time, eccentric bolts can seize, corrode, or deform due to constant exposure to road conditions and torque load. When this happens, alignment accuracy suffers, and adjustment becomes difficult or impossible.
• When to replaces: During suspension servicing or alignment work, When replacing control arms or bushings, If the original bolt is frozen, bent, or corroded
