• 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

Information
Rear control arm hexagon head bolt, M 14 X 100.
Built to factory specs for the rear axle control arms on 996 and 997 models, they deliver the fit and strength your high-performance suspension deserves.
Sold each.
Fits:
Porsche 996 1998 - 2005
Porsche 997.1 2005 - 2008
Porsche 997.2 2009 - 2012
Diagram ref no 18
Thread size / spec: M14 × 1.5 × 100 mm
Supersession: 90037805109, 90037805101
Since the control-arm mounting bolt bears major structural loads and undergoes vibration and torque stress, it can become worn, stretched, corroded or fatigued over time. This reduces its ability to maintain correct alignment and clamping force - potentially resulting in handling issues or component wear. Replacement is especially important when performing rear suspension service, control arm replacement, or alignment work. Installing the correct bolt restores reliable mounting integrity and ensures the rear axle geometry remains stable under load.
